Return Policy

Porcupine Grass (Hesperostipa spartea) is a perennial prairie grass that forms small clumps of leafy stems that lean over to one side after the blooming period due to the heavy weight of the developing spikelets. It forms a branching cluster 4 - 10 inches long at the top of each stem that are linear and needle-like with stiff hairs that cause it to attach to anything that passes by. This grass is initially pale green and once matured it turns a silvery white in the fall. The long awns twist in response to changes in moisture and eventually sow themselves by screwing the seed into the ground.
