Plant Common Name
White Evening Primrose
Fourwing evening primrose is named for the winged fruits that follow the color-changing flowers in spring and summer. A short-lived tender perennial or annual from Texas and most of Mexico, it has now naturalized widely and is often deemed a weed in many subtropical areas.
The bright green leaves are lance-shaped with a point and have uneven edges with rounded sinuses. They, as well as the stems, may or may not be covered in tiny white hairs. In warm temperatures, four-petalled white flowers arise from the stem among the leaves and near stem ends. As the flowers age they become more and more pink and eventually pink-violet when the petals wilt and shrivel. Pollinated by moths, the ensuing fruits are of interest as they are small, brown, hairy, and shaped like a club with four ridges. These seeds will germinate nearby the mother plant, sometimes to the point of weediness.
Grow fourwing evening primrose in average, well-drained soils in full to partial sun. It can be interplanted among rock garden plants or allowed to naturalize with meadow grasses, or grow it in the foreground of a mixed border.
