If you don't know what cactus is, let me explain it to you. This plant, often found in South Texas, is a succulent. A succulent is a plant that can live in very dry conditions like deserts.
Succulents can store enough water to last weeks without rain or some form of moisture.
The most common types of cactus found in Texas are prickly pear and barrel. Prickly pear cactus looks similar to small green saucers that are pasted together and have many prickly spines. Barrel cactus, the second most common type of cactus grown in Texas, resembles a barrel. It is green or brown with small colored flowers on the top it. I think that cactus is the best symbol for Texas.
