Desert Milkweed

Commonly known as Desert Milkweed, Rush Milkweed, or Cane Milkweed. Asclepius subulate is an evergreen perennial that grows striking vertical gray-green succulent stems that bear small linear leaves only after rain and are otherwise naked. From mid-spring to winter, small clusters of white flowers open from creamy yellow buds and provide nectar for butterflies, bees, and other pollinators. Desert Milkweed is also a larval food source for monarch and queen butterfly caterpillars. 

Native to the Southwestern U.S., this perennial is drought and heat-tolerant once established. It is the only evergreen milkweed native to the U.S. Thrives in full sun in sandy, well-drained soils. No serious pest or disease issues. 

This plant is slightly poisonous, and its sap is a skin irritant. Toxic to dogs, cats, and horses. But a vital plant for butterfly gardens.
