Basic information:

Viola adunca, or early-blue violet, is a short perennial with short slender rhizomes. Leaves are alternate, heart shaped to ovate. The flowers of this viola are blue to deep violet, but can often be whitish at the base. Flowers have 5 petals, and bloom from April to August. Fruit are born in capsules with three valves, and the explosiveness of the splitting of the capsules often makes seed collection tricky.

Ecological Importance:

The Mardon skipper (Polites mardon) butterfly depends on Viola adunca as a spring-flowering nectar source. The small orange butterfly is found on two South Sound prairies, and is listed as a State Endangered Species and is a Federal Candidate Species. Zerene fritillaries (Speyeria zerene) also use Viola adunca, but as a larval host. Three subspecies of the Zerene Fritillary are listed on the U.S. Endangered Species List, including the Oregon Silverspot which is classified as threatened in California, Oregon and Washington.

Studies have found that Viola adunca are poor competitors, and are easily displaced by invasive species. Non-native grasses increase thatch density and vegetation height, compete for resources and reduce open space for germination and thus reduce Viola adunca populations. Experiments also show that fire stimulates germination in Viola adunca, and fire could be used to increase Viola adunca populations and provide more area for nectar and larval hosting for butterflies.

Fun facts:

Violet leaves contain more vitamin A than spinach, and a half-cup of leaves has more vitamin C than four oranges! Now, don’t go out and start eating, Viola adunca is a very important larval host and nectar source for threatened butterflies. Another reason to limit consumption: its rhizomes, fruits and seeds are poisonous. Adunca means hooked, and other common names include the hooked-spur violet and the western dog violet.

SPP Plant Profile: Roemer’s Fescue (Festuca roemeri)

By Graduate Research Associate Evan Hayduk

Festuca Roemeri, Roemer’s Fescue

This is the first installment in a new series of pieces we are calling our plant profiles. Over the coming months we will highlight one of the 40 species of prairie or riparian plants that are grown at Stafford Creek Correctional Facility. This is intended to give you an idea of what we are growing, focus on the conservation importance of each species, and offer a few fun facts about each species.

Basic Information: Roemer’s fescue is a bluish, gray-green tufted bunch grass that grows from British Columbia (southeastern Vancouver Island and the Gulf Islands), and west of the Cascade Mountains in Washington, Oregon and Northern California. These areas are typically temperate, with maritime influence. Roemer’s fescue grows from sea level to about 2500 ft. The species is also found in thin-soiled windswept shorelines on the islands of the Puget Sound, the Strait of Juan de Fuca and the Straits of Georgia.

Ecological Importance: A foundation species of the prairies of the Pacific Northwest, Roemer’s fescue is predominately found in the glacial outwash prairies of the South Sound and those which have a history of anthropogenic burning.  Its quick growth makes this fescue an effective ground cover, but its bunch grass nature allows for the growth of other important prairie species, including associated species common camas (Camassia quamash), field woodrush (Luzula campestris), spike goldenrod (Solidago spanthulata), early blue violet (Viola adunca) and prairie lupine (Lupinus lepidus) to name a few.

Who is this Roemer guy anyway? Roemer’s fescue is named for Swiss physician, professor of botany and entomologist Johann Jakob Roemer (1762-1819). Roemer was best known for one of the greatest achievements in the history of Swiss entomology, the Genera insectorum Linnaei et Frabricii. Roemer also published the 16th edition of Carlos Linnaeus’ Systema Vegetabilium.

Blooming Inside the Walls

Blooming Inside the Walls

By Graduate Research Associate Carl Elliott from Stafford Creek Corrections Center

Surrounded by acres of Douglas-fir forest and behind razor wire security fences, a garden tended by the offenders at Stafford Creek Corrections Center is flourishing. Their efforts to cultivate food and flowers has altered the landscape and nourished the spirit of those involved.  These men asked me to provide a documentation of the garden for their families on the outside.  I thought that this service alone was worth providing, but I also feel others outside the prison fence should have the opportunity to see and hear about the garden.

The spring weather on the coast of Washington this year was unusually cool and cool nights persist through July. Night temperatures have rarely stayed above 50° F. The cool weather caused heat loving plants like tomatoes, peppers, and squash to languish.  However, crops such as broccoli, cabbage, peas, and carrots have exploded with growth. The offenders are gathering buckets full of carrots and peas to share with the prison kitchen.

All of the flower gardens were designed by the offenders. They paid special attention to creating habitat for insect pollinators. The plant families they cultivated in the pollinator garden were from the pink or catchfly family, the sunflower family, the pea family, and the mallow family. These plants provide nectar, pollen, and insect prey for beneficial insects.  This is important because the garden is surrounded by concrete which provides poor pollinator habitat.

The other flower gardens include a cutting garden and a native prairie garden. The flowers from the cutting garden are used to beautify the visitor room in the summer. This allows friends and family to see the fruits of the men’s labors and make for a beautiful reception for visitors. The native prairie plant garden overflows with species from the conservation nursery. By seeing the plants they are cultivating for restoration, the men can begin to learn plant families and plant community associations found on the prairies.

The whole garden sits amidst a sea of concrete. Originally, it was a turf covered turn-around for delivery trucks.  Staff grounds keeper, Jon Rydman, took the initiative to open up the space for the men to garden there two years ago.  After a great amount of initial effort to cut the sod, lay the irrigation, and form the beds, the garden was started.  Soil fertility has been improved by compost generated from prison kitchen waste. This unique in-vessel composting system is a pilot project coordinated by plant manager, Chris Idso.  Creating a flourishing garden in a Correction Center requires cooperation and coordination among staff.  The garden produces more than vegetables and flowers; it is also a place for education and change.

Coming Full Circle

Posted by Graduate Research Associate Carl Elliot

The long-term goal of the prairie plant nursery project at Stafford Creek Correction Center (SCCC) is to produce seed to be used in restored South Salish Sea prairie ecosystems.  All of the plants grown at the SCCC nursery are planted out on Joint Base Ft. Lewis-McChord at the seed nursery production unit. Additional seed production beds are at Washington State Department of Natural Resources Webster Nursery. This month the offenders received hundreds of pounds of seed from this nursery to hand clean in preparation for the fall sowing season.  The work provided an excellent opportunity to participate in the full circle of restoration activities.

Lupines were the genus of focus for this stage of the seed cleaning project. The Sustainable Prison Project (SPP) staff delivered bags of seed and chaff of Lupinus albicaulis, Lupinus lepidus, and Lupinus bicolor for cleaning. Cleaning these seeds is a satisfying activity because with a little work they produce a hefty amount of seed. Lupines provide important ecological services as nectar sources and larval food for the Puget Blue Butterfly (Icaricia iracioides blackmorei). They also facilitate the growth of other prairie plants by fixing atmospheric nitrogen. SPP staff led a workshop to educate offenders on the ecological contributions of lupines and basic seed cleaning protocols.

Using a cookie sheet to clean seed

The offenders created a number of unique means to process the seed with improvised tools that they had on hand. Large industrial cookie sheets were turned into shaker tables that allowed the larger seed to roll out and separate from the lighter chaff above. After that initial cleaning, other offenders used the hand sifters we provided to fine clean the seed. Using hand lenses, we identified larval and young adult seed weevils (Thychius germar) that were mixed in with the lupine seed, and dispatched of them humanely. Over the next month offenders are going to build seed screens in the wood shop so we can quickly process seed in larger quantities, and move on to processing wet seed such as Sambucus nigra ssp. cerulea and Viburnum ellipticum.
