Sulcorebutia canigueralii (Syn. Rebutia canigueralii)

Wow! The bi-colored flowers of Sulcorebutia canigueralii are amazing. At least I think so. Earlier in the winter I posted a pic of the plant (without flowers). Now it's Summer, and in addition to a nice, compact, non-hazardous cactus plant, we also get these flamboyant flowers. The warmth of summer may not have arrived yet, but these flowers make up for it. Well, at least a little bit...
