Mahonia haematocarpa is a species of barberry known by the common name red barberry. It is also sometimes called algerita, but that name is more often applied to its relative, Mahonia trifoliolata.

It is native to the southwestern United States and northern Mexico, where it grows in desert chaparral and woodlands, such as in the Mojave Desert of California.

This is an erect, dicot, upright, spreading shrub, reaching up to about 12 feet and almost as wide.

The leaves are several centimeters long and are each made up of a few thick, waxy, lance-shaped leaflets with spiny toothed edges.

The inflorescences bear 3 to 5 bright yellow flowers, each with nine sepals and six petals all arranged in whorls of three.

The fruit is a juicy, edible yellow-orange, pink, or usually redi berry just under 3/8 inches wide.


Quick Notes:

Trunk: Up To About 8 inches to 1 Foot Thick.

Flowers: Small clusters of fragrant yellow flowers borne in upright, clusters of 3 to 7 flowers. Monoecious; perfect, about 1/2 inch in diameter.

Flowering Time: Mid February - April.

Fruit: Edible, tart, yellow-orange, pink, or red berrys in mid-summer, which make good jelly and wine.

Leaves: Alternate, pinnately compound, evergreen, 3 to 5 inches long; 3 to 5, narrow, long holly-like leaflets each 2 to 3 inches long, sharply spined teeth, thick, waxy, gray to blue-green above and paler green below.
