Description: Erect, slender stems are branched above. Alternate leaves are elliptic in outline. Tubular, 1-inch flowers are white, becoming pink as the blossoms age.

Comments: On tall stems, flowers have the appearance of butterflies floating in the breeze. Gaura is from the Greek meaning, “stately.” Long-flower Butterfly-weed is pollinated by moths. It grows in the eastern one-third of the state along roadsides and in rocky, open prairies. Another common species, Velvety Gaura, has soft, wavy-edged leaves and small, rose-pink flowers.
