Big Bluestem

Andropogon gerardii

The Prairie King: Andropogon gerardii (Big Bluestem)


The Snapshot

  • Common Name: Big Bluestem, Turkey Foot Grass

  • Scientific Name: Andropogon gerardii

  • Origin: Native to North America (A keystone species for NJ meadows and restoration)

  • Hardiness: Zones 3 – 9 (As tough as they come).

  • The "Vibe": Grand, structural, and rhythmic; the "Oversized Original."

Why It’s a New Jersey Native Powerhouse

  • The "Turkey Foot" Bloom: In late summer (August/September), the grass sends up flower stalks that branch into three parts, looking exactly like a turkey’s footprint. They often take on a stunning purplish or copper hue.

  • Statuesque Height: This isn't a "border" grass. Big Bluestem can reach 5 to 8 feet tall. It is a fantastic, fast-growing alternative to a wooden privacy fence.

  • Summer Teal to Autumn Wine: The blades start a lush, blue-green or "teal" in the spring and shift into deep shades of burgundy, red, and bronze after the first few cold NJ nights.

  • Unstoppable Roots: The root system of Big Bluestem can go 10 feet deep. This makes it a superhero for erosion control and the most drought-tolerant plant in your entire inventory.

Stories from the Garden

"I have a large property in Hunterdon County and I wanted a 'meadow' look that actually looked intentional. I planted a back row of 'Blackhawks' Big Bluestem. It is spectacular. By August, they are nearly 7 feet tall and they turn this incredible dark purple-black color. They stand up to the wind better than the Miscanthus I used to have, and I love knowing that I'm providing a habitat for local birds and butterflies. It’s a 'power plant' in every sense."

— Jim P., Zone 6 Gardener (Hunterdon County, NJ)


Designer Tips: Where to Plant

  • The "Living Wall": Plant Big Bluestem at the very back of a garden bed to create a tall, shifting backdrop for shorter perennials like Sunflowers or Bee Balm.

  • The Backyard Boundary: If you have a large property, use Big Bluestem to define the edge of your "managed" yard and the "wild" woods. It provides a soft, beautiful transition.

  • The Winter Skeleton: Because the stems are so sturdy, they stay upright all winter. Use them to provide "winter structure" that catches the morning frost and provides a playground for birds.

Designer Pro-Tip: The "Lean Soil" Advantage. Just like Little Bluestem, if you give Big Bluestem too much fertilizer or "rich" garden soil, it will grow too fast and fall over. Plant it in your "toughest" soil and let it struggle a little—it will reward you by standing straighter and having more intense fall colors!


Ecosystem & Wildlife Impact

  • The Nesting Hub: Many native NJ birds use the dried leaves and stems for nesting material.

  • The Pollinator Host: It is a host plant for the Delaware Skipper and other native butterflies.

  • Winter Food: The "Turkey Foot" seed heads provide a critical winter food source for small songbirds.
