Antelope Horn is a milkweed native to Texas, which grows in pastures along roadsides and creeks throughout the central path, that most Monarchs take on their migration coming back up north to the US from Mexico. The milkweed got its name from the seedpods, which look similar to the horns of an antelope. In late Spring, I can find them next to the creek behind our street. And I also find them on the meadows of the local parks. From all the milkweed plants I have seen so far, the Antelope Horn is my favorite.
