The Prickly Pear cactus is the unofficial symbol of Texas and one of the most ecologically important plants in South Texas. Its flat paddle-shaped pads (cladodes) store water efficiently, allowing it to thrive in some of the driest conditions in the region.

In late spring, brilliant yellow flowers bloom along the pad edges, attracting specialist bees and butterflies. By summer, deep red-purple tunas (fruits) ripen and feed dozens of wildlife species.
