Despite the rather tortured taxonomic history of the dwarf globular cacti of South America, there are many very choice collectible plants among them. Sulcorebutia santiaginiensis is one of these, with tightly appressed, interlacing, radial spines. These emerge from the elongate, grooved areoles that are the inspiration for the generic name, Sulco- meaning grooved, and rebut for Pierre Rebut (1830-1898), French vine-grower and owner of a succulent nursery Chazay d’Azergues near Lyon. Coupled with the large, prolifically produced, magenta flowers, these are imminently show-worthy plants, especially in May, and occasionally during surrounding months. Spine color for this species is typically pale yellow and we offer several clones of such forms (HBG 138960, 138961, 138965). In addition, we also offer several clones with pinkish spination (HBG 138962, 138963, 138964). $8.
