Rhipsalis agudoensis...This is a wicked jungle cactus native to south-east brazil and pretty rarely offered, they don't come available that often!
Care: Rhipsalis agudoensis prefer gentle light, these would naturally grow under the jungle canopy attached to trees (epiphytic) so the light would be dappled. Water when the top layer becomes dry but don't' let him dry out completely. These guys like more water and higher humidity than desert cactus as they are native to rainforests, not hot deserts.
Size: Pot Diameter 12cm - Total height is approximately 20cm
Toxicity: Non-Toxic to pets
Difficulty: Easy - More easy indoor plants
Feeding: General, the majority of houseplants should be fed every 2nd watering during the growing season (Spring and Summer), for me, it's about which every 14 days. In autumn and winter, I feed less, as indoor plants will require fewer nutrients.
