Asclepias asperula subsp. capricornu (common name: antelope horns milkweed) have robust flower heads mature into unique horn-shaped seedpods on this early-blooming Texas milkweed that proves invaluable to monarch butterflies migrating north for the summer. Milkweeds are the only plants the butterflies will lay their eggs upon and the only leaves the caterpillars will eat due to their immunity to the plant’s toxins which bioaccumulates in and protects them from predators. The host plant repels deer but can harm curious pets, livestock, and children and should be planted away from their access. Flowers bloom all summer long with deadheading, one plant at a time, to feed adult butterflies, bees, and birds with its energy-packed nectar. Preferring rocky, well-draining soil, do not expect flowers or seeds in the first year while this perennial establishes itself.
