Narrative

Rhizomatous, cool season, perennial grass. Foliage and culms are bluish and glaucus with only partial pubescence on the lemma. Spikes are long and compact with alternating spikelets on the rachis. Roots are fibrous, dense and shallow with a few that extend beyond two feet (0.6m). Similar in appearance to slender wheatgrass and western wheatgrass. It is outcrossed and its' chromosome number is 2n=28. 'Schwendimar' seed germinates in cool soils and develops rapidly. Rhizome growth may not occur the first growing season. If flowers in June and goes dormant with the onset of summer drought. Little regrowth occurs in the fall with the increased precipitation. Growth resumes early in spring and rhizome development increases.For moreinformation click here.
