This attractive member of the Gentian family grows from Central Texas west. It prefers moist places at altitudes under 4,000 feet. It is a low-branching plant 8-12 inches tall, with little foliage, so that the numerous pink flowers grow in a tight cluster, like a bouquet or corsage. Leaves are rarely more than 1/2 inch long, the blossoms 1 inch across. It has an unbelievable number of buds, which continue to bloom for days, even when picked. Blossoms are tubular with 5 starlike lobes and a small white eye in the center.

The brilliant pink corolla resembles that of Phlox species, which have three branches on the style; the style on Centaurium species ends with a small knob or two short branches.
