characteristics

Grows in a distinctive dense mound with outward arching, thin, light green leaves. Delicate pink to brown flowers bloom on panicles well above the foliage. Flowers are notably fragrant; smelling like cardamom. In fall, leaves turn from green to bronze, often persisting through winter. Although slow to establish this is considered one of the most elegant grasses of the prairie.
