3 to 4 feet

Description

A clump-forming perennial, it has long, slender, often reclining stems. Each stem has 10 – 20 pairs of downy, lance-shaped leaves that are up to 5 inches long.

Comments

Found in the southern tallgrass prairie region to northeastern region on savannas and dry to mesic prairies. Rarely used in seeding mixes, even restoration projects, as the seed is extremely small and expensive. The cardinal-red flowers are a good nectar source for hummingbirds.
