antelopehorns milkweed

Asclepias asperula

Honeybees visit antelopehorns milkweed for its abundant nectar and pollen, making it a valuable forage source in arid regions where other blooms may be scarce. Peak bloom occurs in spring from March to May, with sporadic flowering into fall. This drought-tolerant perennial thrives in full sun and well-drained soils, requiring minimal maintenance once established, though it can be toxic to grazing livestock.
