Antelope-horns is a milkweed that spreads out along the ground and grows eight to twenty-four inches in height. It has white sap when cut, hence the name milkweed. The narrow leaves are up to six inches long and appear to be folded at the midrib. The greenish yellow flowers are found in a rounded clump at the end of each stem. Antelope-horns can be found growing in the South Texas Plains in rocky or sandy soils of prairies, pastures, plains, hillsides, brushlands, and woodlands. This plant is poisonous yet has been used for medicinal purposes, boiled like okra, or chewed as gum.
