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 …

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.
