The Story
Plant Bio
Sorghastrum nutans, Indiangrass, is a tall clumping warm-season grass of the North American tallgrass prairie, reaching five to seven feet in flower. Blue-green summer foliage turns orange and bronze in autumn and holds that colour into winter. Narrow golden panicles rise well above the leaves in late summer, catching light from behind.
It is a warm-season grass, so it stays dormant well into spring and only accelerates once the soil is genuinely warm — easy to mistake for a failure in May. Deep roots make it drought-tolerant and useful on slopes once established, and the seed heads feed songbirds through winter.

Planting
How to Grow
- Plant in spring, once the soil has warmed.
- Choose full sun; it flops in shade.
- Space plants about two feet apart for mature clumps.
- Water through the first season while roots go down.
- Leave the foliage standing over winter for colour and cover.
- Cut back to a few inches in late winter before growth starts.
Pro Tip
Do not give up on it in spring — as a warm-season grass it stays dormant until the soil warms properly, weeks after everything else has started.

Common Questions
Indiangrass questions
What zones can Indiangrass grow in?
Indiangrass is hardy in USDA Zones 4–9. Inside that range it survives winter in the ground; outside it, grow it as an annual or a container plant you protect.
Is Indiangrass deer resistant?
Yes — Indiangrass is rated deer-resistant. Deer typically pass it over, though extreme hunger can override any plant's defenses.
When does Indiangrass bloom?
Indiangrass typically blooms in late summer to fall through early fall. Exact timing shifts a week or two with your zone — Sow's bloom calendar maps it to your garden.
Does Indiangrass need full sun?
Indiangrass does best in full sun to part shade. In hot climates, afternoon shade keeps blooms fresher longer.
Is Indiangrass drought tolerant?
Yes — once established (usually after the first full season), Indiangrass handles dry spells with minimal watering. Water deeply its first year to build the root system that makes that possible.
