Description

Green antelopehorn is an herbaceous perennial in the dogbane (Apocynaceae) family that is native to the central and east central United States. It is found in calcareous hammocks, dry woodlands, pine rocklands, and prairies. The Genus name honors Asclepius (Asklepios), the Greek god of medicine; the species name is Latin for “green,” referring to the flower color.

Requires a sunny, well-drained spot and prefers soil with a neutral pH. Propagate from seed.

Best in naturalized areas, meadow, prairie or drought-tolerant plantings; also consider green antelopehorn for butterfly, pollinator gardens, or in a border if there isn't too much competition from other plants.

Insects, Diseases, and Other Plant Problems: No significant disease problems. Most common milkweed pests (aphids, milkweed beetles, Monarch larvae, and milkweed tussock moth larvae) are not problematic, but both large and small milkweed bugs can be very damaging to seed pods.
