Stunning lilies bring beauty and splendor to Cahaba River National Wildlife Refuge in Alabama each spring. Called the Cahaba lily, it blooms from mid-May to mid-June and appears like stars on the landscape. The lily requires a very specialized habitat -- swift-flowing water over rocks and lots of sun -- which restricts it to only a few places. It only grows in Alabama, Georgia and South Carolina and leaves a lasting impression on all who witness them.
