Description

Grafted:
It's a combination of two different cactus species, the colorful top (Gymnocalycium mihanovichii) grafted onto a green rootstock. 
Colorful Top:
The top portion, lacking chlorophyll, displays vibrant colors like red, orange, or yellow. 
Green Rootstock:
Typically a Hylocereus cactus, it provides essential nutrients and support for the colorful top. 
Low Maintenance:
Moon cacti are relatively easy to care for, thriving in bright, indirect light and needing only occasional watering when the soil is dry. 
Compact Size:
They are small, typically growing to only a few inches tall, making them suitable for small spaces. 
Ornamental Value:
Their unique appearance makes them popular as indoor plants and for cactus collections.
