Ptilagrostis

Description

Ptilagrostis is a genus of perennial grasses that belong to the Poaceae family. It is native to North America, particularly in the western region, and is commonly found in dry, rocky areas. The name Ptilagrostis comes from the Greek words “ptilon,” which means feather, and “agrostis,” which means grass. This refers to the delicate, feathery appearance of the grass.
