Oenothera laciniata

Erect to creeping biennial with hairy stems, leaves divided with irregularly lobed margins. Similar to O. grandis but the hypanthium is 15-35 mm long, the sepals are 5-12 mm long, and the petals are 5-18 mm long. It is though to hybridize with O. drummondii where their ranges overlap (Correll and Johnston 1979). Similar leaf to O. speciosa but vein is green.

Frequently found in sandy soils (Shirley 1994). Seed germination for all members of the genus oenothera is reported to be improved by cold/moist stratification (Steffen 1997).

A somewhat weedy species that grows in sandy fields and waste places throughout Louisiana and most of Texas. It is found throughout the eastern United States. It is possible that evening primroses are edible as none have been reported poisonous (Harrington 1967).
