Culture

Easily grown in average, dry to medium moisture, well-drained soil in full sun. Tolerates a wide range of soil conditions. Tolerates clay soils and occasional inundation. Performs well in poor soils. Good drought resistance once established. Tolerates high heat and humidity. Cut to the ground in late winter to early spring. Plant in full sun to avoid flopping late in the season.

Noteworthy Characteristics

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. The foliage turns shades of bronze-orange in the fall. 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. The seeds are eaten by many species of birds.

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.

'Prairie Blues' is grown for its foliage that is more consistently gray blue in color when compared to the species. In fall it has fluffy silver seed heads that may persist into winter and rosy orange foliage. It grows 3 to 3.5 ft. tall and 1.5 to 2 ft. wide.

Problems

No serious insect or disease problems.

Uses

Ornamental grass for borders, cottage gardens, rock gardens, rain gardens, wild gardens, wood margins, meadows or prairie-like settings. Group or mass. A good low-maintenance selection for sun-baked areas.
