AKA Gymnocalycium Mihanovichii, Ruby ball, Neon Cactus and Hotheads.

This vibrant little Cactus can lighten up any space, room, desk and probably your mood too. It’s a green upright cactus with a bright ball-like structure on top, either in pink, red or yellow shades.
The moon cactus is a unique plant because what you see is not a single plant. Instead, it’s two cacti combined into one. The bright top is often mistaken for a flower, but this part doesn’t produce green pigment. It’s a result of human creativity produced by grafting two different cacti together.
