Aristida purpurea
Purple Threeawn
Purple Threeawn is a small bunchgrass to 1 ft. tall, less than 1 foot wide. In summer, the seedheads form a cloud of purple. The seedhead that carries the seed is 3-spoked (3-awned) pinwheel hence the name threeawn. The seed can lodge in pets' paws or ears, so this isn't the grass to use near them. Extremely drought tolerant. Zone 4-8.
