HI blondie202,
Is this the same as your Rick Rack plant?
Zig-Zag Cactus (Selenicereus anthonyanus) If so, it's a cactus and is very drought tolerant. It requires a well draining potting medium and although I grow this plant I don't feel comfortable offering advice to someone else on when or how often to water. Mine hangs outside year round and only gets watered when it rains or if we are having severe drought conditions I will turn the hose on it once in awhile ... but I live in Florida so our humidity is quite high most of the time which helps.
I used to have a very large
Hindu Rope Hoya (Hoya carnosa 'Compacta') and like most Hoya's it's a succulent and also likes a well draining potting medium.
