Description 7
General: Milkweed Family (Asclepiadaceae). Green antelopehorn is a native, perennial forb or herb. Globally, there are 2,000 – 3,000 species in the milkweed (Asclepiadaceae) family. In Texas, there are five different genera in this family, with 35 species in the Asclepias genus. Asclepias viridis is the most common milkweed in Texas ranging from deep east Texas to the Edwards Plateau and typically has wider leaves than Asclepias asperula. They have alternate, entire leaves. The leaf margins are often wavy. Flowers are white and in an umbel, mostly one per plant. Upon close inspection, some rose or purple color is evident in the center of each individual flower (gynostegium). The milky substance that is exuded when a plant part is broken is very sticky, much resembling “Elmer’s glue.” These milkweeds bloom from late spring to middle summer.
Other milkweeds in Texas, such as Asclepias oenotheroides, Asclepias incarnata, Asclepias viridiflora have similar growth habits and flowers, but do not have alternate leaves.
