Evening primrose

Oenothera fruticosa | Rating: 0 votes | Print / Pdf

An impressive herbaceous deciduous perennial, oenothera fruticosa is regarded by many as the most attractive species of the genus. Commonly called the narrow-leaved evening primrose, its most distinctive feature is its narrow, lance-shaped and slightly serrated leaves, which grow along the length of its tall, thick and hairy, dark green stems. In late spring, it produces clusters of large, cup-shaped golden-yellow flowers, with its four lobed leaves featuring pencil-thin dark lines radiating from the centre. The narrow-leaved evening primrose grows best in moderately fertile, well-drained soil in full sun, but spreads quickly in slightly moist conditions. Perfect for gravel beds and rockeries, pruning back after flowering benefits growth.
