Nevin's Barberry is an evergreen shrub native to Southern California foothills. It grows 6-12 feet tall and wide, with blue-green spiny leaves and showy yellow flowers in spring followed by red-yellow berries. Nevin's Barberry tolerates a variety of conditions and provides habitat for birds who eat its berries. It can be used as a landscape shrub, hedge, or barrier plant and requires full sun, well-drained soil, and infrequent deep watering once established.

Family: Berberaceae (Barberry Family)
Native to: Rare in foothills of San Gabriel mountains to Riverside and San Bernardino Counties; San
Fernando Valley Foothills; in sandy to gravelly soils in washes, and on rocky chaparral slopes.
Growth characteristics: woody shrub mature height: 6-12 ft. mature width: 6-12 ft.
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 red-
brown. Moderate growth rate.
Blooms/fruits: Blooms Mar-Apr. Showy, fragrant yellow flowers in loose clusters along branches.

a good jelly) but birds usually eat most of the berries.
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.
Attracts: 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.
Requirements:
Element Requirement
Sun Full sun best; may grow in part shade, but will not flower/fruit as well.
Soil 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)
Water Very drought tolerant once established; better bloom with infrequent deep watering.
Fairly adaptable to garden conditions.
Fertilizer None needed
Other Organic mulch
Management: 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.
Propagation: from seed: yes; fresh seed in fall or cold-treat for spring by cuttings: root cuttings
(dormant in fall) or division of suckers in spring. Leaf cuttings can also be successful.
