The Crownvetch Wars: Planted Prairie Display
Green Co., WI
After extensive site preparation this 18 acre crownvetch infested (30 years
of seed bank) former corn and hay upland was machine planted to four seed
mixes in 2000. Seed blends were designed for soil type, and to withstand
spraying for crownvetch after seeding in the most severely blighted
areas. Results have been gratifying, and careful management, including
annual spring burning and dogged weed control, has paid off with an
especially showy display of many colorful forbs quite thickly planted,
featuring orange butterfly weed, pale purple coneflower, smooth penstemon,
purple prairie clover, and zillions of silphiums! We will also walk through an adjacent 10 acre oak woodland being cleared of brush and invasives for several years now, and overseeded with high hopes. Along the way we can pay our respects to unseeded, but now self seeding, Yellow Giant Hyssop, Agastache nepetoides (Threatened) and a single, unseeded, robust American gromwell, Lithospermum latifolium, (Special Concern). Light refreshments will be served. RSVP.
Time: 5:00-7:00 p.m.
