Antelope Horns

Asclepias asperula

Antelope horns is a low, clump-forming milkweed of open prairies, rocky hillsides and roadsides across the southern and southwestern United States. Its sprawling stems carry pale green and white star-shaped flower clusters through spring, followed by upright curved seed pods that give the plant its name. As a milkweed it is a required host plant for monarch butterfly caterpillars and draws bees, moths and other pollinators to its blooms.
