Sun Drops is an erect, day-flowering member of the evening primrose family. It is native to eastern North America. It typically grows 15-30” tall and produces terminal clusters of bright yellow four-petaled flowers in late spring. Flowers are followed by distinctive club-shaped seed capsules. Flowers bloom during the day, hence the appropriate common name of sundrops. Each flower is short-lived, but flowers bloom in succession over a fairly long period of two months.
