Oenothera wolfii is an uncommon species, restricted to scattered areas along the Pacific coast of south Oregon and north California, where it grows on sandy ground. The species resembles a smaller-flowered variety of oenothera glazioviana, which may derive from oenothera wolfii by hybridization.
The thick, reddish stem bears many narrow leaves at alternate, closely-spaced intervals; these are green withering to red, and have wavy and/or shallowly toothed edges; the teeth are more apparent for leaves higher up the stem. Stems have a covering of fine strigose hairs, and also some longer hairs, red at the base.
Flowers form at the top of the stem; they have four hairy, reddish green sepals about one inch long, and four similar-length yellow petals, becoming orange then red as they wither. The sepal tips are separate when in bud, by about 0.1 inches.
