A hardy alternative to Austrian Winter Peas. Germinates in cooler soils. It is a good weed competitor, does well in heavy soils and fixes 70 - 125 lbs nitrogen per acre. It matures early (in April in warm areas), attracting beneficial insects. If Austrian winter peas are left in until they flower in May, nitrogen fixation may be even higher, up to 200 lb per acre. Mow or roll the crop to kill it after flowering, especially if grown with rye for support, acts as a mulch. Legume inoculant is recommended.
