- Description
-
This is an informal, multi-stemmed, evergreen shrub with irregular, strong upright stems. It grows up to 10' tall, is upright, and is scarcely branching. Showy, fragrant yellow blooms appear in the late winter. Abundant grape-like fruits appear in late summer. This plant has a tiering habit and cane-like growth. It is drought-tolerant and moderately salt-tolerant but is also considered invasive in the southeast. The NC Invasive Plant Council lists this plant as invasive in NC.
The color will bleach out if this shrub is grown in full sun, but does require a few hours of sun per day to flower. It prefers moist, well-drained, acidic soil but tolerates heavy clay. Harsh winds should be avoided. It has very slow growth and is relatively pest free. It will spread by suckers.
Quick ID Hints:
- Odd pinnately compound, stiff evergreen leaves
- Leaflets are sessile, spiny, terminal larger than laterals
- Medium evergreen shrub with tiering habit
Insects, Diseases, and Other Plant Problems: The NC Invasive Plant Council lists this plant as invasive in NC. No serious insect or disease problems. Leaf spots, powdery mildew and rusts may occur. Watch for aphids, scale and whiteflies. See native alternatives to the left.
