It’s always gonna depend on the species of the top half, but the scion on mine grows pups like crazy. Has survived some really clumsily harsh repottings. The soil was full of spider mights and webs…

The moon cactus was my first plant but I find that it grows brown spots, even when being properly taken care of. It doesn’t start to die, it just browns in certain spots. It also doesn’t stand up by …

This gal started off rough. Must have overwatered at first because I was sure the mushy stem was a tell tale sign this one wasn’t going to make it. Left it and now the stem is hardened again. DO NOT …

Very beginner friendly. Doesn't grow excessively fast and the color is very attractive. Does not require much attention as long as you place it near a window and water it when the soil gets very dry.

I love how you can just leave this alone and just water it at least once every two weeks and it won’t even dry up. Very cute and easy to have around if you’re just getting started with house plants.

My moon cactus has gone virtually unchanged in the almost year I’ve had it. Super hardy and always colorful. Imperceptibly slow grower, which can be good or bad depending on what you want out of it!
