Description

Oenothera fruticosa is a day-blooming member of the Evening Primrose family. It produces basal rosettes, and single 15 to 30" rigid stems that are lightly pubescent, tinged with red, and bearing lance-shaped alternate leaves. The flowering stems are terminally branched and produce an abundance of bright yellow poppy-shaped flowers that are up to 2" in diameter. Individual flowers are short-lived, but the blooming period is long, extending for 2 months or more between late-spring and mid-summer. As fall progresses, new basal rosettes will form that will persist through winter, and acquire purple and bronze hues as the cold weather sets in.

Cultivation

Narrowleaf evening primrose is a care-free species and a good choice for tough spaces. It is shallow-rooted and will spread via stolons that are just below the ground's surface. It is however non-aggressive and its spread can easily be controlled by plucking out unwanted plants. Its preference is full sun, but it does remarkably well as a filler plant shaded by taller growing perennials, where the evergreen rosettes will also serve as a green mulch. It is not particular about soil, and will thrive in rich, moist, well-drained ones, just as readily as in poor, dry ones. A smaller, secondary bloom can occur early in fall, which can be encouraged by cutting back spent flowering stems before they go to seed. Zones 4-9

Propagation

Easy to propagate by seed, or by transplanting the new basal rosettes in spring or fall. It can also be propagated by making stem cuttings before the flower buds emerge.
