Black Barrel Cactus
Eriosyce Occulta
I love these tiny black barrels, usually spineless, but when they do have spines, like this one, then they come in black too! Plus, the blooms are red and orange striped. Goohah!
Please note that I don’t think this is one should try to grow. Not because you don’t deserve it, because you do, but because I would be jealous when it blooms and we don’t want any of that.
