Hanging cactus without spikes

Rhipsalis is a tropical succulent native to the rainforests of Central and South America, Africa, and a few islands in the Indian Ocean. It’s the only cactus to grow in the wild outside North and South America. There are some 60 different species, most of which grow on tree trunks. In the wild they flower with a host of white, yellow, orange or red flowers that turn into berries as a result of pollination. This rarely happens indoors. Rhipsalis’s jungle origins make it one of the better air-purifying plants for the home according to research by NASA.
