Sulcorebutia canigueralii (or Dang it's Cold Outside!)

This is Sulcorebutia canigueralii, another archive photo. It's too cold for anything to want to flower here right now. And on top of that, one of our greenhouse heaters went out so I've been out in the greenhouse setting up some temporary heat for tonight until I can fix the other heater tomorrow. Aren't greenhouses fun? And of course, it's going to be the coldest night of the year: 15F (about -8.5C). Begone O Ye wintry arctic cold!
