USDA Hardiness Zones: 4 – 9
Sun: Full Sun (at least 6 hours daily)
Life Cycle: Perennial warm-season bunchgrass
Mature Height: 4' – 7' (taller in rich soils)
Mature Width: 2' – 3' clump
Bloom Season: Late Summer to Fall (showy bronze-gold panicles)
Growth Rate: Moderate to Fast
Summary
A quintessential prairie grass with luminous, late-season plumes and four seasons of presence.
Sorghastrum nutans (Indiangrass) rises in mid- to late summer with stately, upright blades that transition to copper and amber as the season matures. In late summer and fall, arching, bronze-gold panicles shimmer above the foliage, catching evening light and bringing graphic movement to borders and meadows alike. Come winter, its tawny stems stand tall, offering architecture, color, and valuable habitat when most gardens are asleep.
As a warm-season native, Indiangrass wakes later in spring, then surges as temperatures climb—thriving where many cool-season grasses fade. It’s a workhorse on hot, dry sites, yet elegant enough for designed landscapes: pair with echinacea, rudbeckia, asters, monarda, and prairie coneflowers for a pollinator-rich tapestry that spans from midsummer to frost. The clump-forming habit keeps it well-mannered, while the seedheads feed birds and the dense crowns shelter overwintering beneficials.
Low input by nature, it asks for sun, drainage, and space. In return, you get a resilient anchor plant that brings height, texture, and seasonal drama—whether you’re naturalizing an acre or elevating a city border with native flair.
Care
Indiangrass Care
Plant in full sun with reasonably well-drained soil. Water regularly during the first growing season to establish a deep root system; once established, Indiangrass is drought- and heat-tolerant and prefers leaner soils. Overly rich soil or frequent fertilizing can encourage flopping.
Leave stems standing for winter structure and wildlife value. In late winter to very early spring, cut clumps back to 3–6" before new growth emerges. Divide every 3–5 years if vigor declines or to control size.
Feeding is generally unnecessary in average garden soils. If a light boost is desired, apply a spring
slow release fertilizer
sparingly to maintain the plant’s sturdy, upright form.

Additional Information
What is the botanical name of Indiangrass?
Its botanical name is Sorghastrum nutans.
Is Indiangrass deer resistant?
Yes—Indiangrass is typically deer resistant once established.
Does Indiangrass spread or reseed?
Indiangrass is a clump-forming bunchgrass (non-invasive). It may self-seed modestly in open soil; deadhead if volunteers are not desired in highly managed beds.
When should Indiangrass be cut back?
Cut back in late winter or very early spring before new shoots emerge; leaving stems over winter provides structure and wildlife habitat.
