Purple Threeawn is a native perennial bunch grass of North America, but is short lived. It lasts longer than an annual, but not as long as other perennials, depending on care. It spreads by seed and can overwhelm a space if not controlled. It is very drought tolerant.
It has a very soft, feathery look. The stalk is tinted purple and moves in waves in the breeze. It is a striking bunch grass and softens the look of the desert wildflower fields, providing background for wildflowers.
It is native across the southern United States.
Indian ricegrass is a bunch grass, which means it grows as a cluster and is not a spreading grass like turf. It has narrow, rolled leaf blades and is topped with clusters of flowers and seedpods. This cool-season perennial is one of three bunch grasses in the wildflower field that serve as important larval hosts for pollinators, and in sandy soil or scrub, provides stabilization for the sand. It can survive in a variety of habitats and clay soils, although it has a preference for sandy soils. The empty seedpods catch the light and create a glowing effect in bright sun.
The plant is a North American native, with a range extending from southern California up through British Columbia and Alberta and east of the Cascades to Texas and northeastern Mexico.
