Cactus Kate’s San Pedro

“Cactus Kate's San Pedro” is a cultivar of Trichocereus (syn. Echinopsis) known for producing highly glaucous, blue-colored new growth (pups). The spines are characterized by a distinct orange coloration at their bases.

This clone is historically associated with the late Verne Robinson, a well-known cactus vendor who operated under the business name “Cactus Kate.” Specimens of this clone in circulation are frequently traced back to Robinson's original stock.

While specific cultivation requirements for this clone are sparse, it demonstrates robust growth and a strong tendency to pup, even after sustaining physical damage. Standard Trichocereus cultivation practices apply: utilize a highly gritty, well-draining soil mix, provide deep watering only when the substrate is completely dry, and ensure adequate sunlight to maintain the blue coloration of the epidermis.

The community discussion highlights the provenance of the clone through Verne Robinson and describes its key morphological features, specifically the coloration of the pups and spine bases.

Jon Alvarez is assigned a confidence score of 7 because he provides specific morphological details (blue pups, orange spine bases) that align with known characteristics of the clone, and correctly identifies the historical source of the clone (Verne Robinson / Cactus Kate).
