Moon Cactus (Red Cactus)

The ruby ball cactus, commonly known as moon cactus, is a spliced specimen. The colorful red, orange, or yellow top is Gymnocalyciummihanovichii, a name denoting the flower sprouts bearing no hair or spines. The lower green cactus host portion can be any number of species but is typically a Hylocereus cactus. The key function of the lower cactus is to show the Gymnocalycium at an advantageous height.
