Species such as this one, formerly placed in the genus Gaura, are typically rather weedy plants, with leaves borne singly on the stems and frequently in a basal rosette. The flowers are in spikes or racemes, or are branching. They open in the evening. The 4 petals are on the upper side of the flower, giving it a slightly bilateral symmetry. There are normally 8 prominent stamens and 1 pistil; these are on the lower side. The stamens have reddish-brown anthers. The genus is easily recognized, but the species are sometimes difficult, due partly to a great deal of hybridization.
