Psathyrostachys juncea

Psathyrostachys juncea

Russian wildrye

Previous scientific name(s): Elymus junceus, Leymostachys korovinii

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.

Varieties: 
Bozoisky

Developed for vegetative vigor, leafiness, seed yield and seedling vigor. Proven to be significantly more vigorous and productive than Vinall. Winter hardy, drought resistant and widely adapted to western ranges. (Released 1984, source of ecotype: former USSR)

Variety Release Notes: 
Bozoisky II
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)
