Tripsacum dactyloides

(Eastern gamagrass)

This vase-shaped indian grass produces golden yellow plumes, giving 'Indian Steel' a refined appearance. Each flower spike has tiny, bright yellow pollen sacs that stand out on the darker seed heads. From early spring to fall, the foliage is metallic blue, mellowing to a copper-tan after the first frost.

'Prairie Fire' is a distinctly red form from this popular species. The foliage emerges blue-green in spring, but by early summer, the leaves begin to turn shades of deep red. It is unique among switchgrasses because most varieties don't peak until late summer. ‘Prairie Fire’ gradually turns butter yellow in late fall and lingers into winter.

'Hachita' is a vigorous plant with narrow, blue-green leaves that form dense mounds. During summer, the clumps are punctuated by intricate seed heads that resemble eyelashes. This tough, drought-tolerant grass thrives in sand or clay soil with full-sun exposure. It needs good drainage for the best growth. Too much water is often its downfall.

From the prairies of Nebraska comes a refined variety of big bluestem: 'Pawnee'. It has an upright habit and warm fall colors that persist into winter. Each stiffly vertical stem has the characteristic bluish purple cast of this genus. In late summer, 'Pawnee' develops purplish red flowers in groups of three or six, which resemble the foot of a turkey—hence its nickname: "Turkey Foot Grass." Big bluestem has an extensive root system that can extend down more than 10 feet. Each year, a third of these roots die, opening up channels for water.
