Mahonia fremontii is native to mountainous regions of the US states of Arizona, Nevada, California, Colorado, New Mexico and Utah. It reaches a height of up to 3 m, and has pinnate leaves of 3-9 leaflets. Flowers are pale yellow, fruits ellipsoid and dull reddish-purple.The plant was named in honor of John C. Fremont.
Mahonia fremontii is an erect evergreen shrub growing up to 4.5 meters tall. The leaves are several centimeters long and are made up of several holly-leaf-shaped leaflets, each about 2 centimeters long and edged with spiny teeth. The leaves are purplish when new, green when mature, and greenish blue when aged.
The abundant inflorescences each bear 8 to 12 bright yellow flowers, blooming generally in the spring but sometimes in the fall. Each flower is made up of nine sepals and six petals all arranged in whorls of three. The fruit is a berry up to 1.5 centimeters wide, ranging in color from yellowish to purple to nearly black.
Berberis higginsiae is a shrub found only in a small region south and east of San Diego in southern California and northern Baja California. It grows in chaparral and woodland areas at elevations of 800-1200 m (2650-4000 feet).
Berberis higginsiae is evergreen, with thick, stiff compound leaves. It sometimes reaches a height of up to 3 m (10 feet). It is similar to B. fremontii and B. haematocarpa but with narrower leaflets and yellowish-red berries.
