Desert Milkweed

Desert Milkweed, also known as Rush Milkweed or Cane Milkweed, is an evergreen perennial. It has striking vertical gray-green succulent stems that bear small linear leaves only after rain and are otherwise bare. 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 also serves as a 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. and thrives in full sun in sandy, well-drained soils. It does not have serious pest or disease issues. 

Desert Milkweed is slightly poisonous, and its sap is a skin irritant. It is toxic to dogs, cats, and horses, but it is a vital plant for butterfly gardens.
