Asclepias asperula var. decumbens
• Also known as “Trailing milkweed” and “Spider milkweed”.
• Prefers dry, rocky or prairie uplands.
• Flowers March to November.
• As the green seedpods elongate and begin to curve, they resemble horns of antelope.
• The plant will ooze a milky fluid when injured.
• Antelopehorn is toxic to livestock, as are all milkweeds. Due to the unpalatable nature of this plant, poisoning is seldom a problem for livestock.
