Purple Needlegrasss is California's most widespread native grass. It was named California's State Grass in 2004.

Purple needlegrass gets its name from the color of its young seeds. It is a perennial bunchgrass that can grow up to 3 feet tall. It has a deep root system, which makes it drought adapted and a good plant choice for erosion control.

Purple needlegrass is easy to grow and tolerant of most soil types, including poor and disturbed soils. Plant in full or part sun as part of a low-water meadow garden. This grass produces a large amount of seeds, which attract birds and other wildlife. It has long awns, and pet owners should be aware that they are prickly. It can be cut back when it turns brown at the end of summer.
