Oenothera fruticosa

Oenothera fruticosa, narrowleaf evening primrose[1] or narrow-leaved sundrops, is a species of flowering plant in the evening primrose family.

It is native to much of eastern North America,[2] where it is found in a variety of open habitats, including dry woodlands, rock outcrops and moist savannas.[3]

It is an erect herbaceous perennial growing to 20–90 cm (8–35 in) tall, with alternative, simple, entire or slightly toothed leaves. The saucer- or cup-shaped yellow flowers, 2.5–5 cm (1–2 in) in diameter, appear in late spring and summer.[4] The fruit is a capsule that is strongly 4-angled or winged and shaped like a club.

Many varieties have been named, but the infraspecific taxonomy of this species is still in an unresolved state.
