Noteworthy Characteristics:
Blue grama grass is a clump-forming Missouri native grass which is typically found in dryish soils on upland prairies and along railroad tracks. It is an important component of the short grass prairies of the Great Plains. A diminutive species of grass which features narrow leaf blades and unique flower spikes which are attached at right angles to the stems and resemble mosquito larvae. Flowers bloom reddish purple in summer on stems rising above the foliage to 20" tall. At frost, foliage turns purplish then tan. Also commonly called mosquito grass.
No serious insect or disease problems.
Uses:
Small size makes blue grama grass an excellent selection for rock gardens where it can be used as a specimen or in small groups. Also an excellent choice for naturalized areas, native plant gardens, unmowed meadows, prairie areas or other informal areas in the landscape, especially where drought tolerant plants are needed. Can also be grown as a turf grass and regularly mowed to 2 inches high.
