RE: Cactus in bloom - Sulcorebutia Canigueralii
Sure looks like the corona of a flame in the colors. Very rare and lovely photos.
By the way, what sort of stones is it growing in? Lava rocks? They look super porous.
Thank you! It does looks like fire indeed.
Yes, those are lava rocks but just on top. This year I actually didn't use it.. I just added some sand on top, but mixed some lava with the soil for extra drainage.
