Correll's bluet (Houstonia correllii) is a small, prostrate, mat-forming wildflower in the coffee family, known only from Zapata County in southern Texas, where it bears white flowers. It is a rare native species rather than a common garden plant, so it is best grown in conditions that mimic its dry, sunny South Texas habitat.
