Forget what comes to mind when you imagine a cactus because epiphytic cacti do not grow in the sand and do not have large spikes.
Epiphytic cacti are members of the Cactus family (Cactaceae). They are native to South and Central American rainforests and grow at altitudes ranging from 3,000 to 5,000 feet (900 to 1,500 m).
Unlike most cacti, which live in arid, desert conditions, epiphytic cacti growing in rainforests may receive up to 157 inches (400 cm) of rainfall annually.
They are called epiphytic because they grow on other plants, although they are not parasites. With their roots, they anchor themselves in the crotches of tree branches, where organic matter tends to collect and decompose. This light, loose medium allows water and oxygen to reach the roots of the plant, which absorb the water and dissolved nutrients.
Various species of epiphytic cacti with interesting foliage and spectacular blooms are currently available. Schlumbergera (Christmas Cactus and Thanksgiving Cactus) cultivars are easy to find and come in many colors. Hatiora (Easter Cactus) cultivars are increasingly popular, as are cultivars of Epiphyllum (Orchid Cacti). Their names generally refer to the season when they bloom.
There are many species of epiphytic cacti, and they all thrive under the same growing conditions. Look for the following genera: Rhipsalis, Selenicereus, Disocactus, Hylocereus, and Weberocereus.
Understanding what makes epiphytic cacti unique will help you make the best decisions concerning their care. They need a well-draining medium with lots of air space and thrive as houseplants because of their relatively low lighting requirements. Unlike desert cacti, epiphytic cacti should be kept damp but not soaking wet. Allowing them to dry slightly between waterings is also acceptable.
