 Many species are in bloom in March and April, but with so many examples, some variety is usually in bloom at any time.A wildscape garden was installed around the visitors' center in 2004, with a trickling fountain and trees, shrubs, and flowering plants native to the Chihuahuan Desert.The aim is to provide a place where birds, small mammals, and other local wildlife can find food, water, and safety from predators to raise their young.
