Psathyrostachys juncea* (Russian wildrye)

Formerly known as Elymus junceus. Cool season, perennial bunchgrass with extensively developed root system. Adapted to fertile, fine textured soils. May be difficult to establish, but once established it is extremely drought tolerant. Starts growth in very early spring and after ripening produces abundant green forage throughout summer and fall. Excellent palatability to wildlife and livestock.

Boizoisky Select & Boizoisky II - Developed for improved vigor, leafiness, seed yield, seedling vigor and forage yield. Bozoisky II selected for even greater seedling establishment. (Released 1984 & 2006 respecitvely, source of ecotype: former USSR)

Swift - Adapted for gazing in the Canadian prairie and the northern Great Plains region of the U.S. Good curing qualities make it especially useful for late summer, fall and early winter grazing. Emerges from deeper plantings and develops larger and more vigorous plants in the establishment year than other Russian wildrye varieties. (Released 1978, source of ecotype: Canada)
