Moon Cactus
Gymnocalycium
Moon Cactus, or Gymnocalycium, are brightly colored, eye-catching, cacti. Since the toppers are grafted onto dragonfruit cactus, you’ll water them more often, as you would a tropical cactus.
Most Popular Types
These fun cacti come in pink, red, orange, and purple. We’ve even seen some that look like they’ve been tie-dyed!
Light
Full sun
Temperatures
The dragonfruit can withstand temperatures down to 33°F, but only for short periods of time.
Watering
For gymnocalycium in its natural state, water only when the soil has been completely dry for a week or so. For the grafted varieties (colorful balls on top of green dragonfruit cactus stems), water every 2-3 weeks.
Toxicity
Non-toxic to people and pets.
Growth
In nature, gymnocalycium is earth-toned. These colorful toppers are mutant hybrids lacking chlorophyll, needing to be grafted on dragonfruit segments to receive nutrients.
Origin
Paraguay and Argentina
Propagation
You’ll see offsets growing from the colorful ball topper. These offsets will not survive if removed, unless they are grafted onto a base plant. If the base plant grows additional limbs, it’s best to remove them and grow them into a separate plants – or use them as base plants.
Dormancy
Winter dormant
Gymnocalycium mihanovichii moon cactus
Gymnocalycium mihanovichii, the moon cactus, has been genetically engineered to create colorful cacti. Because it can no longer produce chlorophyll, it is grafted onto a dragonfruit cactus for nutrition.
