The state grass of Illinois, Big Bluestem once dominated the Midwestern prairies. It has a tall, upright growth habit. Blue-green foliage turns an attractive red-orange in the fall. Finger-like flowerheads are purple and give it the alternative name of Turkey’s foot. Stems hold up in the winter, and the seeds are a good winter food source for birds. Big Bluestem’s deep root system helps it survive drought and break through clay soils. It is an attractive native grass that is great for a natural look.
