Wildflowers of the Mojave Desert: Cylindropuntia Bigelovii

The teddy bear cholla, cylindropuntia bigelovii, is a familiar sight in the Mojave and Sonoran deserts, often forming great colonies containing thousands of plants. Stems are stout, short, and many branched, covered by barbed spines that are white or light yellow when young, becoming dark brown when aged. Flowers are less bright than for some other chollas - greenish yellow in color, borne at the tips of the stems in spring and early summer.
