Purple Three-Awn

Aristida purpurea

Aristida purpurea, also known as purple three-awn, is a native perennial bunch grass that can add both aesthetic and ecological value to an Arizona pollinator garden. This grass produces airy, purple inflorescences that are attractive to native bees, such as bumblebees and sweat bees.

By incorporating Aristida purpurea into a pollinator garden, gardeners can not only enhance its visual appeal but also support the populations of important pollinators in their area.
