7 Nurseries Carry This Plant

About Giant Stipa (Stipa coronata) 7 Nurseries Carry This Plant Achnatherum coronatum is a greenish species of grass known by the common name crested needlegrass. It is native to southern California and Baja California, where it grows on the coastal and inland hills, often in chaparral plant communities. This is a perennial grass forming loose bunches up to about two meters in maximum height, but usually shorter. It is similar to its relative, Achnatherum parishii, and the two intergrade in many characteristics and are easily confused. The grass bears a generous flower cluster up to 60 centimeters long with large spikelets up to 2 centimeters long each, not including an awn of up to 4.5 centimeters. The awn has two distinct kinks.
