Sorghastrum nutans (L.) Nash
Indiangrass, Yellow Indiangrass
Poaceae (Grass Family)
Synonym(s): Andropogon nutans, Sorghastrum avenaceum
USDA Symbol: SONU2
Yellow indian grass is a tall, bunching sod-former, 3-8 ft. in height, with broad blue-green blades and a large, plume-like, soft, golden-brown seed head. This showy perennialís fall color is deep orange to purple.
This is a beautiful grass with a somewhat metallic golden sheen to its flowering parts. It is an important associate in the tallgrass prairies and is relished by livestock. It appears to be favored by occasional flooding and repeated burning and sometimes forms nearly pure stands in the lowlands. Warm-season grass with rich gold-and-purple sprays of flowers and seeds in the fall. (Ontario Native Plants 2002)

Conditions Comments: Along with little bluestem, big bluestem and switchgrass, Indian grass is an important species in the tallgrass prairie. The bright yellow flowers contrast attractively with the blue-gray foliage. The grass stays low most of the year and then gets tall before blooming in early autumn. Like little bluestem, Indian grass is best planted en masse or in a wildflower meadow.

PropagationPropagation Material: Seeds
Description: Propagate by sowing unstratified seed in fall or stratified seed in spring. Sow 1/4" deep. Division of older plants is difficult because of a dense, tangled root system.
Seed Collection: Collect seed in fall.
Seed Treatment: Seeds require dry stratification.
Commercially Avail: yes
Maintenance: Indian grass tolerates imperfectly drained soil. It is a good accent plant, however it needs tall companions to remain upright.
