This evergreen shrub, Rhamnus crocea, is typically one to two meters in height.[1] R. crocea typically occurs in chaparral, with common flora associates being Toyon and Hollyleaf cherry.[2]
Rhamnus crocea covers two major mountain foothills. In California, it surrounds the entire San Joaquin Valley, the pacific coast ranges and the western foothills of the Sierra Nevadas. In Arizona, it is found in the entire length of the Mogollon Rim to the western region of the White Mountains.[3]
The fruit of Rhamnus crocea was used as food by Native Americans in the Western United States. [4]When eaten in large quantities, the berry is reported to impart a red tint to the entire body of the consumer.[5]
