Schizachyrium scoparium, commonly called little bluestem, is native to prairies, fields, clearings, hills, limestone glades, roadsides, waste areas and open woods from Alberta to Quebec south to Arizona and Florida. It was one of the dominant grasses of the vast tallgrass prairie region which once covered rich and fertile soils in many parts of central North America. It typically matures to 2-4’ (less frequently to 5’) tall, and features upright clumps of slender, flat, linear green leaves (to 1/4“ wide), with each leaf having a tinge of blue at the base. Purplish-bronze flowers appear in 3” long racemes on branched stems rising above the foliage in August. Flowers are followed by clusters of fluffy, silvery-white seed heads which are attractive and often persist into winter. Many consider the most outstanding ornamental feature of this grass to be its bronze-orange fall foliage color.
Genus name comes from the Latin schizein meaning to split and achyron meaning chaff.
Specific epithet means broomlike.
Common name is in reference to the lavender-blue color on the stem bases.
'MinnblueA', commonly marketed under the trade name of BLUE HEAVEN, is a little bluestem cultivar that is noted for its blue-gray foliage, burgundy-red fall color and narrow upright plant form. It typically grows in a clump to 2-4’ tall. Erect, broom-like clumps of slender, flat, linear leaves (1/4” wide) emerge light blue in spring, darken to blue-gray in summer, acquire purple highlights in late summer before turning burgundy red with pink and purple tones in fall. In July-August, flower stems rise higher than the foliage clump bearing small reddish-brown flowers. Flowers give way to seed heads fringed with showy, silvery-white hairs. Seed heads may persist into winter. Foliage eventually fades to beige in winter. BLUE HEAVEN was introduced by the University of Minnesota at St. Paul, Minnesota. U. S. Plant Patent PP17,310 was issued on December 26, 2006.
No serious insect or disease problems.
Ornamental grass for borders, cottage gardens, wild gardens, wood margins, meadows or prairie-like settings. Group or mass. A good low-maintenance selection for sun-baked areas.
