Sundrops is a native, perennial, erect, day-flowering member of the evening primrose family. Although it is striking when seen along roadsides and in meadows, it never achieves the beauty possible under cultivation. It is also found in dry forests, glades, and rock outcrops. 
Sundrops prefers moderately fertile, dry, well-drained soil in full sun but will tolerate some shade. It can spread quickly in ideal situations yet isn't terribly aggressive. The yellow flowers are short-lived and occur in succession over a long period. This plant was named the 1989 NC Wildflower of the Year.
