Cactus Kate's Bridgesii

*Trichocereus bridgesii* specimens identified as “Cactus Kate's Bridgesii” typically present as robust, columnar cacti forming dense, multi-stemmed patches. The epidermis exhibits a glaucous blue-green to light green hue. Rib count generally ranges from 5 to 7 on mature stems, with some younger growth potentially showing 4 to 5 ribs.

Cactus Kate, whose full name is Kate, operated Desert Theatre Nursery in Watsonville, California, initially in partnership with her husband, Jay Jackson. Following their separation, Kate continued to run Desert Theatre in Watsonville. Jay Jackson subsequently established a separate entity, Desert Theater Nursery, in Escondido, California. This Escondido nursery was later acquired by Brandon Bullard and remains operational today.
