Gaura is a genus of 20–25 species of annual and perennial herbs confined to the warmer regions of N. America.: leaves. alternate, sessile or stalked, entire, dentate, or sinuate: flowers. white or rose, in spikes or racemes; calyx tube deciduous, obconical, much prolonged beyond the ovary, with 4 reflexed lobes; petals clawed; stamens mostly 8, with a small scale-like appendage before the base of each filament; stigma 4-lobed, surrounded by a ring or cup-like border: flower. nut-like, 3-4-ribbed, finally 1-celled, and 1-4-seeded. Gauras are easily propagated by seed. They prefer light soils, and the seedlings can be transplanted directly into permanent quarters.
