Oenothera fruticosa

Narrow-leaf evening primrose, Oenothera fruticosa, is native to eastern North America, where it grows in open landscapes such as dry woodland, rocky outcrops and grasslands. It bears lance-shaped, fresh green, alternate leaves and large saucer-shaped, bright yellow flowers. Unlike many species of Oenothera, its flowers bloom throughout the day.

There are a few cultivars of Oenothera fruticosa available, such as ‘Fireworks’, which has dark yellow blooms opening from red buds, and 'African Sun’, which has a rounded, compact habit.

Perfect for container displays and bedding schemes, grow Oenothera fruticosa in a sunny, sheltered site in well-drained soil. If soil is likely to become wet in winter, consider transplanting under glass until spring.
