Family

Onagraceae

Botanical Name

Oenothera fruticosa

Plant Common Name

Narrow-leaved Evening Primrose

General Description

This is a loosely clumping perennial with upright branching red-tinged stems, lance-shaped leaves, and large bright-yellow cup-shaped flowers in summer, three to ten per cluster,that open by day and are followed by winged seedpods. Low tight rosettes of leaves may persist over winter in warm climates. It is native to most of the eastern half of the U.S.

Narrow-leaved evening primrose grows and flowers best in full sun on average, well-drained soil. It tolerates dry conditions once established and can spread quickly in open, moist soil. This is a good perennial for summer bloom in a bed or border.
