A narrow-stemmed, warm-season bunchgrass that can get up to 7ft tall if left un-mowed. Originally from Sudan, generally dies off well over winter in the Northwest. It is great for increasing soil organic matter, cycling nutrients, and suppressing weeds. Deeply penetrating roots also loosen soil and reduce nematode and symphylan populations as they decompose. It requires warm soil to germinate and can be planted when these conditions are available in late spring through mid-summer. Cornell University recommends an seeding rate of 30 lb/acre for biomass and nematode control or a 50 lb/acre for weed control.
A vigorous, viney, annual legume that produces sizable amounts of green matter, attracts beneficial insects and provides good coverage for weed suppression. It is also commonly used for forage and can be planted well as part of a mix with small grains or ryegrass. Can be seeded in spring or fall at rates between 40-60 lb/acre.
A purple, nectar-rich flower with a long flowering period. It is a great attractant for bees and beneficial insects. As a cover-crop it is easy to manage, fast establishing, weed-suppressing, with a long and planting window through spring, summer and fall. Seeding rate is around 4 lb/acre.
