Evergreen woody shrub with stiff branches and a rounded top. Leaves are blue-green, tapered and spiny (like a holly). Shape is mounded, dense and spreading. Branches are an attractive redbrown. Moderate growth rate. Growth characteristics: Blooms Mar-Apr. Showy, fragrant yellow flowers in loose clusters along branches. Fruits is a striking yellow-red to red berry, to 1/3 inch long, in summer/fall. Fruits are edible (make a good jelly) but birds usually eat most of the berries. Blooms/fruits: Uses in the garden: Most often used as an evergreen shrub. Works well in a mixed border, or as a hedge, screen or barrier plant. Outside the garden it is often utilized along roadsides, fence-lines, slopes, and upland riparian areas. Tolerant of wide range of garden conditions. Good accent plant with showy blooms/berries and interesting leaf-shape & color. Nice along sunny south-facing walls. Sensible substitute for: Non-native hollies, barberries; other large dense upright shrubs. Excellent bird habitat plant. Provides good cover (even the cats don’t like the spiny leaves) . Berries are a favorite for berry-eating birds incl. Towhees, Mockingbirds, Cedar Waxwings. Attracts: Requirements: Element Sun Soil Water Fertilizer Other Requirement Full sun best; may grow in part shade, but will not flower/fruit as well. Any well-drained soil – not particular; any local pH is fine, but probably does best with slightly acidic. May benefit from organic mulch (pine needle or redwood bark) Very drought tolerant once established; better bloom with infrequent deep watering. Fairly adaptable to garden conditions. None needed Organic mulch Prune to shape – even shear as a hedge. Young plants will become fuller with tip pruning (pinching) to increase branching. Remove dead branches. Severely prune to rejuvenate. Management: Propagation: from seed: yes; fresh seed in fall or cold-treat for spring (dormant in fall) or division of suckers in spring. by cuttings: root cuttings Leaf cuttings can also be successful.
