Oenothera speciosa (Onagraceae)
A hardy, upright to sprawling perennial, native to the southeastern United States extending into Mexico. The four petalled flowers are soft pink, making a transition to glistening white toward the center. Flowers open in the early morning lasting only a single day. In many southern regions they often form large breathtaking colonies. Grows in various soils in full sun. A fun variety to grow from seed but takes two years to produce a bloom.
