Oenothera wolfii is a rare species of flowering plant in the evening primrose family known by the common name Wolf's evening primrose. It is native to the coastline of southern Oregon and northern California , where it grows in coastal prairie, dunes, and coastal forest and woodland habitat. As of 1997 it was known from only about 16 occurrences.[2] The biggest threat to the plant is its easy hybridization with its relative and probable descendant, Oenothera glazioviana.[2] As this rare wild plant crosses with the introduced garden escapee, introgression occurs, causing what is known as genetic pollution; fewer pure individuals of O. wolfii will be seen as they are outnumbered by hybrids.[2]
Oenothera wolfii is a hairy biennial herb producing a dense rosette of leaves and an erect stem up to a meter tall. The wavy or toothed leaves are up to 18 centimeters long. In its second year the plant produces an inflorescence, a spike of showy yellow flowers with petals one or two centimeters long. The fruit is a capsule which may be almost 5 centimeters in length.
