Grusonia grahamii

Grusonia grahamii (Engelm.) H. Rob.

Graham's Pricklypear, Graham Dog Cactus, Graham's Club Cholla

Cactaceae (Cactus Family)

Synonym(s): Opuntia grahamii, Opuntia schottii var. grahamii

USDA Symbol: GRGR6

USDA Native Status: L48 (N)

The Graham dog cactus often forms low mounds with many branches. The last joint on the branches is erect and widest near the top, about 2 inches long or less. It has rough, wartlike structures on the joints, giving the plant a rough, dull appearance, an unlikely place to find the attractive yellow flowers it produces. The flowers open in the early afternoon. The joints of this plant, like those of other chollas, break off easily and hang on to anything that barely touches them.
