Direct sow in fall in rocky, alkaline, or sandy, well-drained, dry soil in full sun — antelope horns is the iconic native milkweed of the Texas Hill Country, southern prairies, and Chihuahuan Desert, producing clusters of unusual, intricate flowers with green-white petals reflexed back to expose greenish-maroon hoods, giving the flower cluster an otherworldly appearance. The large, broad, horizontally spreading leaves are gray-green and waxy; the paired seed pods curve upward like antelope horns, full of silky-plumed seeds in late summer. It is one of the most important early-season monarch butterfly host and nectar plants in Texas, as it emerges and blooms in spring before other milkweeds are available during the critical spring migration period. Antelope horns is a deep-rooted perennial of great drought tolerance and longevity — once established in adapted caliche, limestone gravel, or dry clay it requires virtually no care or supplemental water and lives for decades.

Direct sow seed in fall in very well-drained, rocky to sandy, alkaline to neutral, dry soil in full sun; antelope horns has a large taproot that makes it drought tolerant once established but very difficult to transplant — direct sowing in its permanent location is strongly preferred.
