The balls of flowers of antelope-horns are a very familiar sight along Texas highways. This is a very common plant of open areas in most parts of the state except for the deep east and south. It is generally a low-growing, spreading plant that is not obvious until it flowers. Like most of the many other milkweeds of Texas, it has a milky sap that is poisonous and that can even cause skin rashes on contact in some people.
