This colorful selection carpets large sections of Altman’s wholesale succulent nursery with blazing color. Other forms of this species have been long cultivated like the pale yellowish form. The name S. adolphii was recently confirmed to have priority over S. nussbaumerianum, by Miguel Chazaro, et al. in 2010, in the Cactus and Succulent Journal 82 (1): 5.Though often seen with two “i”s, the proper spelling of this epithet should have a single “i” as this is the genitive form of Adolphus, the Latinized name for Adolf Engler, who was director of the Berlin-Dahlem Botanical Garden where the type plant of S. adolphi was growing at the time of its description in 1912. A solid coppery-orange form was distributed as ISI 1682 that was subsequently named 'Coppertone'. 'Firestorm' reads as a similar color in the landscape but closer inspection reveals golden-yellow leaves with orange margins. Rooted cuts of HBG 120336, $5.
