It is native to the southwestern United States, where it occurs in the Sonoran Colorado Desert in far eastern San Bernardino County in southeastern California and in the Sonoran Desert region in southwestern Arizona (Yuma, La Paz, Pima and Maricopa counties).[4]

It occurs in shaded, rocky canyons in the mountains, at an elevation of approximately 800–1000 meters.[5][6]

Description

edit

This plant is a rounded shrub usually growing up to 1.5 meters tall, sometimes reaching 2 meters. The leaves are trifoliate, with three spine-tipped leaflets each a few centimeters long. The inflorescence is a dense cluster of up to 11 flowers. Each bright yellow flower has 9 sepals. The fruit is a juicy blue-black berry about half a centimeter wide.[3]

The compound leaves place this species in the group sometimes segregated as the genus Mahonia.[5][7][8]
