The milkweed family is full of very beautiful plants with intricate, orchid-like flowers. This is just one of a dozen or so species of Asclepias that are native to Texas. As most people know, they are the milkweeds that play host to Monarch butterfly larvae. They all produce elongated pods that release fluffy wind-borne seeds. A. perennis grows in and around wet areas. The individuals I found were growing in one of the retention ponds of the Forest of Friendswood neighborhood.
