RE: Cacti that grow in trees

I didn't realize how much I love these types of succulents...
and epiphytes in general!
When I first discovered Easter cactus I was blown away by a white 'aster like' flower. Very different from the other more closely related two. There's only one left (and it might be Hatiora sp.) in my home. I can't seem to keep it happy, so maybe now I'll just treat it even more like an orchid!
