When growing in the wild, the evening primrose acts as a primary colonizer, quickly appearing in bare, undisturbed patches of ground. It self-sows freely. The blossoms on this plant are yellow and open in the evening...hence the name evening primrose! The evening primrose is a very popular plant in ornamental gardens!
