Let's Get (Native) Planting!

Black Huckleberry

Spring is definitely in the air- little bits of green life are starting to make their brave entrance into the world, the piles of snow that once towered are shrinking by the minute, and we at Cascadia are starting to think about our springtime projects.

The main one I want to touch on today is our Native Plant Sale and Workshop. This year we are offering nine different species of Native Plants. These plants are grown from Eastern Washington seed stock by the Washington Association of Conservation Districts Plant Materials Center in Skagit County. Plants offered include Ponderosa Pines, Vine Maples, Black Huckleberry and Red Osier Dogwood, among others. These plants are commonly used for restoration, soil stabilization, and some are considered to be fire resistant. A brochure describing the uses and benefits for each plant is linked to our website, along with an updated plant listing, and order form. Plant orders are due by March 4^th and can be mailed into the Cascadia Conservation District office with a deposit. Once ordered, you can pick up your plants on April 16^th from 10am to 1pm at the Stemilt Growers Warehouse in North Wenatchee.

Ponderosa Pine

If you are interested in ordering Native Plants, but have no idea how to best utilize them on your property then you may be interested in attending our Native Planting 101 Workshop. This FREE workshop is taking place on March 5^th from 12 to 4:30 pm at the PUD Auditorium on N. Wenatchee Avenue. This workshop is perfect for landowners in our district who are interested in learning techniques to effectively use native plant species to encourage pollinators, restore damaged areas, and create a low maintenance yardscape. It may be particularly useful for property owners who lost vegetation in last summer’s fires or for those who are seeking to become more FireWise. The workshop features presentations on Yardscaping, Pollinators, Restoration, and Integrated Weed Control Methods by local plant and natural resource experts. Workshop attendees will have an extended deadline of March 11^th for ordering plants from the Native Plant Sale. You can register for this free event on our website!

Serviceberry

If you are interested in either of these events you can find more information on our website, cascadiacd.org. Our Native Plants are selling out quickly, so if you haven’t already had a chance to make your plant selections, I strongly urge you to do so as soon as possible! We are also looking for more volunteers for both of these events- if you are interested in volunteering send an email to americorps@cascadiacd.org.

Wild and Scrumptious

Continuing with our native plant theme, and considering several of our native plants for sale are edible, it seems appropriate to devote a blog to edible native plants. Before delving into this topic, I’d like to be clear that eating plants found in the wild holds some risk and should not be done in a casual manner. If you’re a novice identifying plants or are unsure, it’s best to get a second or third opinion from someone in the know before munching down.

There are many benefits to eating wild plants. First of all it’s free, and as someone on a tight AmeriCorps budget, I’m all for free. Also, generally speaking, plants lose nutritional value the longer they sit after being harvested. So you get more bang for your buck when you eat freshly harvested plants. Depending on values and disposition, it’s also common that people gain a deeper appreciation for the things they eat when they’re able to see their food in its natural environment and gather it themselves.

Being a novice in the subject myself, it seems the best place to start is with plants that are relatively easy to identify and have no poisonous lookalikes. It’s also recommended that one learn the few poisonous plants around in order to better avoid them. The following are just a few examples of the many tasty edible plants you can find in our area:

-Evergreen Huckleberry produces edible berries, which are commonly used to make delicious jelly and jam.

Evergreen Huckleberry (Vaccinium ovatum)

-Hooker’s, or tapertip onion has edible flowers and bulbs and can be consumed raw or cooked. While raw this onion is said to be overpowering, it’s purportedly sweet and delectable when cooked.

Hooker's Onion (Allium acuminatum)

-Camas also has edible bulbs which can be eaten raw or cooked. When cooked, they’re known to be sweeter than a sweet potato. The bulbs can also be ground into flour. It should be noted that Camas has a deadly lookalike aptly named "death camas". To avoid any fatal mix-ups, double, triple or even quadruple check to be sure you've got the right camas. It's easiest to distinguish one from the other while they're flowering.

Camas (Camassia)

-Wild licorice was commonly used by Native Americans. They have sweet, fleshy roots which get sweeter when cooked.

Wild Locrice (Glycyrrhiza lepidota)

If you’re like me, your mouth is watering just thinking about those scrumptious local flora and you can’t wait to get out and try your hand at finding, preparing and devouring such delicacies. And, if you’re a novice like me, you probably need to pump your breaks, hard. Not only is it the wrong time of year to be gathering many of these edible plants, but there are also some guidelines everyone should abide by when harvesting wild plants. This list of dos and don’ts is from the Washington State University Snohomish County Extension website (http://ext100.wsu.edu/snohomish/wp-content/uploads/sites/11/73aEdibleWildPlants.pdf):

• Know what you are picking
• Collect only what you can positively identify as edible
• Harvest only plants that look healthy in uncontaminated areas
• Clean and prepare wild foods like you do cultivated crops
• Eat only small quantities when first trying an edible plant
• Get property owners' permission before gathering wild foods
• Never over-harvest. Take only what you can use and use what you take.

If this blog has convinced you to take up gathering wild edible plants, there are plenty of resources online to help you get started. There are also some great field guides worth their weight in edible flora such as A Field Guide to Edible Fruits and Berries of the Pacific Northwest by Richard J. Hebda and Edible and Medicinal Plants of the West by Gregory L. Tilford.

While it’s been raining down here in Wenatchee, the higher elevations have been getting snow which has increased our snowpack in this area to 64% of the 34 year average (ftp://ftp.wcc.nrcs.usda.gov/data/water/wcs/gis/maps/wa_swepctnormal_update.pdf).

Icons of North Central Washington

With this post we’ll conclude our look at the native plants offered by the Cascadia Conservation District. If you’d like to see the full plant list, make an order or get more information please visit our website.

These final two plants are symbols of our region. The grand ponderosa pine (Pinus ponderosa) and the vine maple often come to mind when thinking of healthy ecosystems in our area.

My favorite tree of all time, icon of the west and reigning top seller in our plant sale is the ponderosa pine tree. Ponderosa pine, colloquially ‘pondo’, is characterized by its orange, scaly, plate-like bark and long green needles which are typically borne in bundles of three. Growing to around 100 feet in mostly open stands, ponderosas often have the appearance of dominating their surroundings. They are also known for smelling like vanilla.

Very well adapted for our climate east of the Cascades, ponderosa pine isn’t just fire tolerant, it depends on fire. With its thick bark a large ponderosa can handle the low intensity fires that were ubiquitous to this area prior to modern forest management. These fires eliminated the pondo’s resource competitors, allowing it proper exposure and sufficient resources. Since management plans have included enthusiastic fire suppression, shade tolerant trees and shrubs have moved into ponderosa stands throughout the west, lending such stands the characteristics necessary for the increasingly large scale fires we’ve been seeing as of late.

As for conservation uses, ponderosa is commonly used in shelterbelts, living snow fences and in riparian restoration. Ponderosa stands make great habitat for squirrels, birds and bats and provide shelter for big game. Because ponderosa needs exposure, it is a seral species which, when mature, can provide the necessary shade for shade tolerant species to return after a significant disturbance. This makes it an excellent native plant choice for post fire restoration.

Vine maple (Acer circinatum) is another iconic native plant in our region. It is a deciduous tree with red and white flowers in the spring, and brilliant red to subdued yellow broadleaves in the fall. Typically vine maple will grow between 10 and 30 feet tall, with shaded specimens reaching the upper end of that range readily and exposed specimens on the shorter side.

Vine maple grows best along streams and moist sites. It prefers shady sites, but can tolerate some exposure.  In more exposed sites it often takes a single-stemmed tree form, while in shade it usually grows as a shrub in clumps and thickets.

With its white and red flowers in the spring and showy colors in the fall, vine maple is a common choice for those looking to use native species to beautify their landscaping. It is also used as a streamside stabilizer, as a pioneering species at disturbed sites and is an important food source for birds and large and small mammals alike.

Again, if you’re interested in ordering any of our plants, need more information or would like to sign up for our native planting workshop, please see our website.

Today’s Central Columbia River area snowpack is currently at 63% of its 29 year average (USDA/NRCS National Water and Climate Center, http://www.wcc.nrcs.usda.gov).

Broadleaf Bonanza

For this week’s blog we’ll examine three broadleaf shrubs: the Oregon state flower, a red-barked soil retainer and stinky white flowers. Remember, these are but three of Cascadia’s 14 native plants for sale. To make an order, see a complete plant sale list or sign up for our free native planting workshop, please see our website.

Oregon Grape

Oregon Grape

Oregon grape (Mahonia aquifolium), Oregon’s state flower, is my favorite shrub in this year’s sale. With a waxy texture and sharp leaflets, its evergreen leaves strongly resemble those of ivy. Oregon grape produces dense clusters of small yellow flowers followed by tart, dark blue berries. It typically grows three to six feet tall and five feet wide.

Oregon grape will grow in a variety of settings, from the coastal range to the eastern slopes of the Cascades. It can grow in soils from moist to dry and at exposed to shady sites, but is especially well adapted for drier, exposed sites which makes it a great restoration species. It propagates via suckers and has an extensive root system, making it an excellent soil stabilizer. Birds and rodents are attracted to the berries and the new growth and leaves can be a food source for elk and deer.

Red osier dogwood (Cornus sericea) can grow to about 20 feet tall and 20 feet wide. It has thin, waxy, red bark with green deciduous leaves that turn red in the fall. In the spring it grows the beautiful white clusters of flowers characteristic of dogwood.

Red Osier Dogwood

Red osier dogwood often grows in dense thickets along riverbanks and is found much more sparsely at higher elevations and drier sites. While it prefers plenty of exposure, it will tolerate shade. It’s proclivity for moist soils and open sites and its extensive root system make it a great streamside restoration plant. It can stabilize soil as well as provide shade and habitat for fish. Its foliage is also an attractive food source for elk and deer.

Blue Elderberry

Blue elderberry (Sambucus nigra ssp. cerulea) is one of the largest shrubs we offer growing up to about 30 feet tall and 20 feet wide. It dawns white flowers in the spring which are aesthetically pleasing but emit a slightly rancid smell. These smelly flowers give way to purple or black, waxy berries. It has long, narrow green leaflets up to six inches long. 

While it can grow in a variety of habitats, blue elderberry does best on exposed sites. It’s an early seral species, but can persist beyond initial succession. In conservation, blue elderberry has a number of uses including riparian restoration, erosion control and habitat improvement.

Thanks to a brief, though much needed storm last weekend, the Central Columbia River area snowpack is currently at 71% of the 29 year average.  More specifically, as of January 1, the Wenatchee River drainage was at 68% of its 29 year median.  (USDA/NRCS National Water and Climate Center, http://www.wcc.nrcs.usda.gov). 

Three More Native Beauties...

I’d like to use this post to continue the tour of native plants offered by the Cascadia Conservation District. If you’d like to place an order, get more information or register for our native planting workshop, please see our website. Two of these next three native plants, woods’ rose and golden currant, are old plant sale standbys, while evergreen huckleberry is back for the first time since 2012.

Woods' Rose

Woods' rose (Rosa Woodsii), or Interior rose, grows in a variety of soils and climates, even in places with very little topsoil and at high elevations. It does well in varying degrees of sun exposure. It should also be mentioned that wild roses are far less susceptible to disease and recover much quicker than domesticated roses.

The woods’ rose is an excellent choice for someone looking to beautify their property in a harsh climate. As well as being a hardy survivor, it also dawns magnificent pink flowers and bright red hips. Because of its ability to grow with little soil on steep slopes and in generally tough conditions, the woods’ rose is a top choice for restoration.

Evergreen Huckleberry

Evergreen huckleberry (Vaccinium ovatum) is another hardy plant we offer. Though it is commonly found in coniferous forests and prefers shade, it can grow in full sunlight and sandy soil and it is drought tolerant.

In the spring the evergreen huckleberry, in ideal conditions, will grow light pink, urn-shaped flowers which will transform into delicious red, then purple berries. Its leaves are egg shaped, dark green and have a reddish hue when immature. The evergreen huckleberry grows up to 13 feet tall.

Golden Currant

Golden currant (Ribes aureum) is a deciduous shrub that grows up to 6 feet tall and 6 feet in diameter. Its waxy green leaves turn a showy yellow in the fall and the shrub produces yellow flowers which morph into berries of various colors.

Golden currant can grow in a variety of sites, from moist bottomlands to exposed hillsides making it a good soil stabilizer for nearly any location. Also, while its berries may taste tart to us, but they’re a favorite for birds and small mammals.

Today’s snowpack as a percent of average is 64% (USDA/NRCS National Water and Climate Center, http://www.wcc.nrcs.usda.gov).

Plant Sale Wrap Up

We've finished up the plant sale for the year (most of the way at least), and I feel like doing a short recap of the related activities over the past few weeks. The plant sale has provided ups and downs throughout the year with its time commitments. Early in the fall preparing the outreach materials and order forms, and then again recently with the bundling and distribution have been time intensive. Late fall and winter were fairly easy with only the occasional order to enter in the computer. We sold all our stock except for a few quaking aspens. There were even a few species that were so popular that we had to order in more of them.

A few weeks ago in March we held our bundling event. Plants are shipped to us in large bags with a single species per bag. We have to take the plants out of those bags and fill our customer orders. Not all the plants are shipped in the correct sizes either. Some plants are shipped 50 to a bundle, which means we have to pull apart those bundles and shrink them to our sale size of 10 plants per bundle. Once all plants are in the correct bundle size we fill the orders by placing the plants into large garbage bags. Damp sawdust is added to each bag to help moisten the roots. A name tag is attached and the finished bundle is placed in a bin. Once all the orders are filled the bins are put back into the cold room to await the distribution day.

 Last Saturday marked the distribution/pick up day for our Native Plant Sale. Customers that had placed orders with us throughout the fall and winter were finally able to receive their much awaited plants. We arrived early to lay out all the plants alphabetically so we didn't have to waste time digging through the bins trying to find a certain order. All but a few people arrived during our three hour time slot to pick up their plants, and we've been working to get the last few orders into their owner’s hands. Hopefully by the end of this week all the orders will be accounted for.

So with the end of the plant sale in sight I can say I’m glad to be wrapping it up for the year and putting it on the shelf. I’ll add in my thoughts and any advice I can think of, and I’ll leave it in the binder for next year’s Americorps to have fun with.

Spring is Here

March 20^th marked the first calendar day of spring, and this year nature is willing to follow along. Temperatures have warmed from the cold, snowy February weather. The hills are starting to green and soon wildflowers will be blooming. The sun peaks through the clouds and warms the air.

Balsamroot

Picking a calendar day seems an arbitrary way to start a season, and it is. We choose to set our seasons by the solstices and equinoxes as a convenient way to mark the changing of seasons. Luckily we live in an area that they happen to coincide fairly well. But if you head north or south of our latitude the seasons start to follow a different path. I doubt spring in Alaska has really started yet, nor is winter a measly three months long. Head south to the tropics and the overall temperatures rarely change. Seasons there may be more accurately described as wet/dry. Head far enough south into Australia or South America and the seasons are opposite of ours. As we head into spring they head into fall.

Yellow Bell

Spring around Wenatchee is an amazing time of year. The hills lose their brown or yellow color they sport much of the year and show off their lively green. Green represents growth in the shrub steppe environment, both annual and perennial. Spring is often the only time of year there’s enough moisture available for plants to grow and thrive in our climate. The combination of melted winter snow and spring rain provides enough moisture for plants to survive the rest of the year in this two to three month period.

Buttercup

Not only do plants use spring as a time to grow. They also use it as a time to flower. One of the easiest to spot is the balsamroot, which sports large yellow flowers that seems to blanket portions of the hillsides. Lupine is quite prominent as well, featuring tall stems covered in purple flowers. Look close enough at your feet while walking between the sagebrush and you might notice yellow bells, bluebells, lomatiums, and buttercups.

Besides the prominent flowers are a variety of grasses. Much of the bright green you see comes from their spring growth. Most people consider grass a staple of lawns, requiring constant moisture to survive and thrive. That’s not the case. Native grasses thrive in our environment with no watering by us necessary. Even when the grass has lost its fresh, green look come June and July it’s still alive. Simply waiting to sprout again come the following spring when there’s plenty of moisture.

I encourage you to go out and enjoy the shrub steppe during the spring. In my opinion it’s the only time to truly appreciate the great variety of life present. Come summer and fall all that will be left is a dry, brown hillside with little shade to get out of the sun. Enjoy it in the spring when it’s still cool and the hills are alive and colorful.

Plant Structure

 Plants exhibit great variety. Cacti in the deserts, pines in the mountains, water lilies in a pond, and wheat in a field. Yet among all these different types of plants there are basic structures shared by nearly all of them. Almost all plants have a root system and a shoot system. Root systems are composed of roots (obviously) and shoot systems are composed of leaves and stems. Regardless of the overall morphology (form and structure) of a plant they all rely on these structures to survive and thrive.

Roots serve a few purposes. They anchor the plant in the ground. Roots allow redwoods to grow hundreds of feet into the air. They provide the support that keeps riparian vegetation from washing out during a flood. Roots also provide the entire plant with water. Roots pull the water out of the ground and transport it to the rest of the plant through its vasculature system. Roots are also responsible for the uptake of nutrients that the plant needs in large and small quantities.

Stems represent the (generally) aboveground structures that leaves sprout from. Stem structure is composed of a series of nodes and internodes. Nodes are the point where leaves sprout. The internodes are the space between. Stems have two types of buds present. (A bud is the point where new stem growth occurs.) A terminal bud represents the growth point of a stem. Usually a terminal bud is located at the furthest point along a stem or branch. An axillary bud is located between the leaf and the stem at the node. Axillary buds have the potential to form lateral stems, or branches. Rhizomes are a type of underground stem that travel under the surface and sprout up away from the original plant. Strawberries spread through rhizomes. Even though rhizomes grow under the soil they are not roots.

Leaves grow out from stems and for most plants are their primary site of photosynthesis (the process by which plants convert sunlight into energy). However, some plants, such as cacti, have modified leaves into needles, so most of their photosynthesis is carried out in the stems. Flowers evolved from leaves into the great variety we see today.

Plants have three main types of tissue. Most of these tissues are present in all plant structures, but their function and morphology varies from the roots to the leaves. The three types are ground, vascular, and dermal tissue.

Dermal tissue is all the tissue on the outer layer of the plant. This tissue is responsible for protecting the plant from physical damage and pathogens. Leaf dermal tissue helps regulate the loss of water and the intake of CO₂. Root dermal tissue helps capture water and minerals in the soil. Non-woody plants are covered in an epidermis. In woody plants the epidermis is replaced by periderm in older parts of the plant.

Vascular tissue is responsible for transportation of materials within the plant. The flow usually goes from roots up to shoots, and from the shoots down to the roots. Xylem is the vasculature responsible for transporting water and dissolved minerals and nutrients throughout the plant. Phloem is vasculature responsible for transporting organic nutrients that are produced in the photosynthetic areas of the plant (generally the leaves) and to the roots or sites of new growth.

Ground tissue is all the other tissue in the plant. This tissue is responsible for most plant functions: photosynthesis, storage of nutrients, growth, and support. Ground tissue in the leaves is mostly responsible for photosynthesizing. Ground tissue in the stems, branches, or trunk is responsible for much of the plant support. Ground tissue in tree trunks is often dead and is strictly there to support the outer part of the trunk that is still alive and filled with vascular tissue.

When it’s broken down to the basic level a plant is built from three basic structures: roots, stems, and leaves. These three structures are composed of three types of tissue: ground, dermal, and vascular. These six things make up the basics for almost all plants. That’s amazing when all the variety of plants are considered. 

Plant Diversity

This week I want to start a series of articles spanning the next few months delving into the world of plants. I've written briefly about different species of plants, their uses, and some of their importance in a healthy ecosystem, but now I want to dive into the different structures, types, and functions found across them. Most people understand that trees, bushes, grasses, ferns, mosses, crops, and flowers are all considered plants. While many of these look vastly different from each other they share many common visible structures and internal mechanisms. This week I’m going to start with an overview of the variety of plant classes in the hopes of giving a basic intro.

Moss (Bryophyte)

Hornwort (Bryophyte)

First, let me provide a definition of a plant. Plants are embryophytes. The name comes from the way they protect and nurture the embryo inside the parent structure. This definition excludes algae and other things that may have been included with a less specific definition. Most plants are terrestrial (living on soil), but some species have evolved back into the water (such as water lilies and duckweed). All are complex, multicellular organisms. All plants are non-motile (they can’t move). Photosynthesis is their primary means of producing energy, but a small number are parasitic. Plants also display an alternation of generations between a haploid gametophyte (a multicellular generation with a single set of chromosomes) and a diploid sporophyte (two sets of chromosomes present).

Quillwort (Lycophyte)

Clubmoss (Lycophyte)

Plants can be further divided into two groups, those reproducing and spreading through spores: bryophytes (liverworts, mosses, and hornworts), lycophytes (clubmosses, spikemosses, and quillworts), and monilophytes (ferns and horsetails); and those reproducing and spreading through seeds: gymnosperms (conifers, cycads, gnetophytes and ginkgoes), and angiosperms (flowering plants). Plants can also be divided into those with vascular tissue (specialized tissue in the plant the transports water and nutrients around): lycophytes, monilophytes, gymnosperms, and angiosperms; and those without specialized vasculature: bryophytes. (Don’t worry about understanding the ins and outs of plant reproduction or tissue yet. I’ll make sure to cover them in detail in later posts.)

Fern Frond (Monilophyte)

Horsetail (Monilophyte)

Bryophytes include mosses, hornworts, and liverworts. They are grouped together based on their lack of vascular tissue, and are therefore referred to as non-vascular plants. However, they do not form a monophyletic group (a group made of an ancestor species and all its descendants). Instead they are more likely a paraphyletic group (a group made of an ancestor species and its descendants minus one or more monophyletic groups). In this case they are made of embryophytes minus the tracheophytes (plants containing vascular tissue). Bryophytes lack true leaves, stems, and roots. They are among the most primitive of land plants. They require almost constant moisture to keep from drying out as they lack many features that more advanced plants use to keep from drying out.

Lycophytes are represented by clubmosses, spikemosses, and quillworts. They still reproduce primarily through spores, but they have vascular tissue, and therefore; leaves, roots, and stems. They are more advanced than the bryophytes.

Monilophytes are made up of ferns and horsetails. They reproduce through spores, have vascular tissue, leaves, roots, and stems. They are the closest relatives to the seed plants.

Welwitschia 

(Gnetophyte, Gymnosperm)

Ginkgo (Gymnosperm)

Gymnosperms are composed of four different groups: conifers, cycads, gnetophytes and ginkgoes. Gymnosperms are more advanced than the previous groups because they produce seeds instead of spores for their primary reproduction. Gymnosperms are known as naked seed plants because their seeds are not enclosed. Even though they’re typically in cones for general protection, the seed itself is not encased. Conifers are made up of many common and important species including pines, firs, cedars, and junipers. They represent many of the largest plants on earth. Cycads generally have stout, woods trunks with a crown of leaves at the top. They can be confused with palm trees, but they are not closely related. Gnetophytes have some characteristics, such as vessel elements, not found in other gymnosperms. Ginkgoes are represented by one species of plant, Ginkgo biloba, and have been present on earth for millions of years virtually unchanged.

Quaking Aspen (Angiosperm)

Rose (Angiosperm)

Angiosperms make up everything else. They are the most common plants, representing some 250,000 species on earth. They have flowers, vasculature, stems, roots, leaves, and enclosed seeds. Orchids, maples, oaks, roses, apples, grasses, and many other common plants are all angiosperms. It’s important to keep in mind that not all flowers are showy and easily noticeable. When’s the last time you looked at a field of grass and pointed out its flowers? I assure you they are present, and when I get to the post on flowers I’ll cover it in much more detail.

Of course this is just the tip of the tree when it comes to all the fascinating aspects about plants. I realize that not many things are explained in detail here, but that’s not really the point for this post. The importance here is to understand the great diversity found in the world of plants. They started as very simple organisms, basically land versions of green algae. From there they evolved up to giant redwoods and flowering roses. There are many common characteristics, of course, but also a great deal of differences in them. Over the next few months I hope to introduce and explain features found in plants, and explain the differences. 

Native Plant Sale: Part 3

It’s the first week of January. The weather doesn’t feel much like winter though. The last few days have brought temperatures in the low to mid 40s, and the snow has been lacking. It feels more like November or February outside right now. Regardless, it’s time to take a look at the last four plants in this year’s Native Plant Sale.

Blue elderberry is the sixth shrub for sale this year. The range of this shrub covers the western parts of North America north into British Columbia and south into the northern parts of Mexico. They favor damp areas along streams, rivers, and other open, wet locations. They grow best on moist, well-drained, and sunny locations. It works well as a stream bank and eroded site stabilizer. The blossoms on elderberry are white and will bloom between May and July depending on local climate. The berries that mature in late summer into the fall are quite edible and have been used for makes preserves, pies, and wine. Click here to read a previous blog outlining some of these uses. Many birds and animals will also eat the berries. It can reach sizes of up to 25 feet tall, but is more common to reach sizes around 10 feet. 

Red osier dogwood is the seventh shrub available this year. This dogwood is present in most of the US and Canada. The only area it’s not present is in the South East US stretching over to Texas. They are usually found growing in moist soils along rivers, swamps, creeks, and lakes. Even though they prefer moist soils they don’t like completely saturated soil for long periods of time. Red osier is useful for stream bank stabilization. The plant is most noticeable in the winter when its bright red bark adds color to a winter landscape. It flowers in late spring with clumps of small, white flowers. It is also useful as forage for animals in the winter, and its berries are eaten by some bird species. It can reach heights of 20 feet, and will often grow in thickets due to the rooting ability of its stems. A more in depth look at red osier can be found here.

Tall Oregon grape is the final shrub offered this year. Its distribution ranges throughout the Northwestern US and extends up into British Columbia. It can grow in a variety of soil and terrain types, from dry to moist, and from sunny to shady. Oregon grape can be found as an understory species in wooded areas, or as the one of the first species growing in a disturbed area. The plant develops a large root system with time, so it can be useful for soil stabilization. Many rodents and birds enjoy the berries, and young stems and leaves may be eaten by deer and elk. It also has many ornamental qualities including bright yellow flowers in spring, purple berries in late summer, and reddish green leaves throughout the year. It will grow to roughly 10 feet in height, with an approximately equal amount of spread.

Kinnikinnick is the only ground cover for sale this year. Its range covers Canada and much of the Northern and Southwest US. It grows best in course soil that is well drained. It grows in forests and on sand dunes, acting as a very effective soil stabilizer due to its spreading nature. It tolerates cold very well. The fruits on the kinnikinnick are eaten by some birds and game animals. Deer may browse it lightly as well. Its leaves are dark, shiny green. The flowers are small and white to pink in color, blooming in late spring. It is a low growing plant, generally staying under 6 inches in height, but it can spread out 15 feet.

This concludes my look at all 12 plants offered for sale this year with our Native Plant Sale. If any of these plants sound intriguing make sure to order some today! There’s a little bit of everything available. Conifers, deciduous trees, shrubs, and ground cover will provide everything you need to landscape or restore your property.

Come back next week for another article.

Native Plant Sale: Part 2

It’s the beginning of December and the snow is starting to fall as I sit writing the blog for this week. Frankly it’s about time. There’s something incredibly relaxing about watching the snow fall. As much as I would love to dive into talking about snow, I must save it until a little later in the winter. It’s the beginning of the month and therefore time to return to the topic of our Native Plant Sale and talk about four more plants we’re offering.

Quaking Aspenn

Quaking aspen (Populus tremuloides) is the second deciduous tree that we’re offering this year. Its range includes all of Canada, most of the United States except for the Southeast, and down into Mexico. Quaking aspen prefers to grow in soils that stay moist most of the year. It can grow in some areas with less moisture, but will not reach the same growth potential. The trees can reach up to 90 feet in height with adequate moisture, but will often remain under 40 feet, especially in drier sites. The tree gets its name from the way the leaves move in the wind. The stem shape of the leaves causes them to “quake” in even a light breeze. The leaves are a very pleasing green color through spring and summer, and in fall they turn a brilliant yellow. Aspens stabilize well, but sprouts will grow off of the roots.

Mock Orange

Mock orange (Philadelphus lewisii) is another one of the eight shrubs offered for sale this year. The range of mock orange includes Washington, Idaho, Oregon, Montana, California, British Columbia, and Alberta. It prefers well-drained, moist soils. It can be found in areas ranging from riparian to open or forested lowlands to rocky upland sites. It reaches heights ranging from six to ten feet with a spread of roughly six feet. Mock orange flowers anywhere from May to June. The blooms are white and give off a sweet smell making this shrub quite pleasant to have nearby when in bloom. This shrub is very useful for soil stabilization.

Snowberry

Snowberry (Symphoricarpos albus) is the fourth out of eight shrubs offered this year. The range of snowberry includes the coastal mountains of the west coast, north into British Columbia, and east over to New England. It can grow in sun or shade, and in a variety of soil types including stream banks, moist clearings, and open forests. It grows from three to eight feet tall with an approximately equal spread. The flowers are white to pinkish. The berries are white during the summer and change to a darker color as they ripen. The berries are considered to be poisonous, so don’t eat them.

Woods Rose

Woods rose (Rosa woodsii) is the fifth of eight shrubs for sale this year. This rose has a range that covers western North America as far north as Alaska, south into Mexico, and east to Iowa and other Midwest states. It can grow in sunny or moderately shady sites. It is adapted to a range of moisture levels on site from riparian zones to dry grassy slopes. However, it grows best in moist, well-drained soils and on sites that are open. It grows roughly six to eight feet tall with an approximately equal spread. The flowers are various shades of pink and it blooms anywhere from May-July. Woods rose is useful for erosion control due to its rhizomatous root system that spreads out and helps stabilize the soil.

Of course by the time I finished writing this blog the sun was out and the snow has stopped without really any of it accumulating. Sigh. There will always be another day for more snow to come though. This concludes the brief look at these four plant species. Eight plants down, four more to go in the beginning of January. If any of these species interest you make sure to visit our website, download the available forms, and place your order!

Until next week,

Seed Dormancy

Some seeds have this odd thing about them. They don’t sprout at the first moment that conditions are ideal. Why would they do this? It increases the rate of their survival. These seeds are in a state of dormancy. This isn’t the same as hibernation. Hibernation is something that an organism chooses to go into. Seeds don’t choose to enter dormancy when winter is coming or the soil dries out. They have no choice. It’s something they start out in. Dormancy keeps seeds from sprouting during decent conditions because it’s forcing them to wait until a time they’d have a better chance of survival.

Do all plant species produce seeds that go through dormancy? No, because not all of them need to. A seed dropped during October isn't going to sprout. The conditions aren't ideal for germination (the point when a seed sprouts and the plant first starts growing). It’ll wait until the spring and then it will sprout up. Also, seeds from plants living in areas with a fairly constant year round climate (such as an equatorial rainforest) can often be non-dormant. The conditions on any given day are so similar to any other day that there’s no reason to go through dormancy.

However, a seed dropped in August may need dormancy. September might be a damp, warm month, and a non-dormant seed might thing it was okay to sprout. And for a few weeks or a month it might grow just fine. At least until it started to drop below freezing and started snowing. At that point the seedling would probably die. However, with dormancy the seed is prevented from sprouting during the fall. Some mechanism in the seed prevents it from sprouting until it receives a signal canceling the dormancy. The dormant seed then rides out the winter safely, and it’s not until spring that it finally sprouts and grows. Instead of having a month or two to grow in the fall, this new seedling will have six or seven months to grow. This extra growth might make all the difference in the plant’s survival.

Seed dormancy can take a variety of forms and require a variety of cues in order to be broken. These forms include physical, physiological, morphological, morphophysiological, and combination dormancy. The cues can vary wildly, anything from a period of cold to one of heat, a time of dryness to one of dampness. Let’s take a brief look at each of the different forms.

Physical dormancy is probably the simplest form. In this form water is blocked from entering the seed by the seed coat. It’s only after a period of time and environmental factors that the seed coat is made permeable (allows the passage of water). At this point the seed can germinate once favorable conditions arrive.

Physiological dormancy is caused by internal chemical suppression of germination. The environmental factors might be favorable for growth, but the cue has not come to release the stranglehold on germination. This cue (at least in our area) often takes the form of a certain time length of cold temperatures. In much hotter climates this could be reversed and require a period of high temperatures. Other seeds might require a period of darkness, one that might only occur in the short days of winter, or with snow cover.

Morphological dormancy is a product of having seeds that can’t germinate because they’re not ready yet. The plant dropped seeds that were not yet developed enough to germinate. The seeds need time on the ground just to reach the point where germination could start.

Morphophysiological dormancy is a combination of physiological and morphological dormancy. The seedling is both underdeveloped and chemically prevented from germinating. This means that one of the environmental cues must occur and then a period of time must pass before the seed will sprout.

The final form is a mix of physical and physiological dormancy. The seed has both a water impermeable seed coat and it requires environmental cues to allow germination.

Think about the work it’s taken to grow what we want, where we want, and when we want. The seeds we buy to plant in our gardens aren’t always non-dormant varieties. Many of them had their innate dormancy bred out of them by humans selecting for seeds that germinated easier. Other seeds may need to be tricked into thinking that all their environmental cues had been met. They may be dried out and put in a fridge for a few months, put in a dark room, or kept warm for a few weeks. Think of the effort it takes to trick these seeds into growing for our needs. And that’s not to say we know how to trick all plant seeds. There are still species we don’t understand which cues they need to break dormancy.

The Fungi

What comes to mind when you think about fungi? Perhaps it’s mold on a bread slice, a bright red mushroom on the forest floor, or maybe you’re not sure what a fungus is. Regardless, fungi are so much more. Not only are the visible portions of a fungus usually just a small part of a larger organism, but many fungi are difficult to see because they’re under the soil, inside a tree, or microscopic. The truth is fungi are everywhere.

of the entire underground fungal growth.

Mushrooms may be easily visible, but they’re only part of a larger system. A mushroom is simply the fruiting body of the larger, unseen mycelial mat. (A mycelial mat is the portion of a fungus not usually seen by human eyes. It’s responsible for uptake of nutrients and water and for most other functions as well.) Mushrooms are responsible for releasing spores into the air. The spores then travel on air currents in the hopes that they land somewhere with the right conditions to allow for growth of a new fungus. While a single mushroom cannot show the true size of the underground mycelium, a group of them might be able to. This is seen in fairy rings where the mushroom ring outlines the entire area of growth.

Walking through a forest you often see fallen trees and other debris rotting on the floor. What causes that debris to rot? Fungi. And it’s a good thing too. If that material didn’t rot and break down the forest floor would slowly accumulate more and more stuff. Eventually the floor would be so full that nothing could grow up through the choking mass of debris. The only things that would survive would be the trees already present, but even they would eventually die. At some point all the trees would die and nothing would be left except a pile of dead logs and accumulated leaf litter.

Decomposition (the same thing as rotting just a more technical term) is important for two main reasons. One, as mentioned above, it helps break down debris and keep the ground clear. Two, by breaking down the debris it returns the nutrients in forms that can be reused by other plants. Without this cycling of nutrients plants wouldn’t be able to grow and thrive regardless of the availability of space on the forest floor. Fungi’s roll in decomposition makes it one of the most important players in the plant cycle. Without fungi the cycle would stop.

While decomposition of fallen trees and debris is generally good for still living and future plants, rotting of living tissue is not. Some fungi will infect a tree and start breaking down the inner part of the tree. The tree may look perfectly healthy and then one day fall over. And it won’t be until it’s fallen over on the ground that you can tell it had been rotted from the inside out.

Fungi can also help plants grow and thrive in environments that might normally be inhospitable to a plant. Fungi do this through a mycorrhizal association with the roots of a plant. This association is symbiotic between the plant and the fungus. (Symbiotic relationships are when two or more species form a close working relationship, often for long periods of time. These relationships can take different forms: benefit all; benefit one and hurt another (parasites); and benefit one without hurting the other.) The fungus is able to pull water and nutrients out of the soil that the plant may not be able to get at for a variety of reasons: soil pH, water content, etc. The fungus then transports these to the plant’s roots where the plant exchanges the nutrients for carbohydrates.

Not all fungi are helpful though. It’s estimated that more than 80% of all plant diseases are caused by fungi. These diseases cover a broad spectrum of symptoms and effects. Some fungi simply infect a few leaves and don’t hurt the overall health of the plant, but others can start on a leaf and quickly make its way through the whole plant. Destroying the plant host as it goes.

Most plants and fungi in an area have evolved together over time. The fungi come up with a new way to infect, and the tree responds with a new defense. In general this keeps them fairly well matched. Fungi still infect certain specimens, but most are able to fight off the infections. The issue arises with introduced pathogens. Fungi from other continents might present challenges to native species. Diseases like Dutch elm disease and sycamore anthracnose are the result of fungi that were introduced into areas with plant species that had no defenses to them. This has led to the death and disfigurement of large numbers of both elm and sycamore trees.

Next time you’re out walking around I hope this blog helps you understand the role of fungi in your life. Remember that many things in life wouldn’t be possible without them. They help the plants grow and through them help us as well. And while fungi do cause many problems, their positives far outweigh their negatives. And last, but definitely not least, without fungi in the form of yeast we would have neither bread nor beer. Mull about that next time you’re sitting in a brewery/bakery enjoying the fruits of a fungi’s labor.

As always tune in next week for another informative article.
