It can grow up to 1 foot (30 cm) tall, and each individual stem segment may be around 2 inches (5 cm) long.
It produces magenta flowers which are under an inch (2.5 cm) wide across, and deep green, small berries.
7. Selenicereus grandiflorus (Queen of the Night)
This impressive plant can produce huge aerial roots (link), giving it an excellent grip on trees. It grows abundant stems that trail over other plants, and it tends to require support from them.

The Easter Cactus is a popular houseplant treasured for its uniquely shaped leaves and red flowers.
It grows branching stems that are formed of multiple sections, and it can reach about 25 inches (63 cm).
It can be grown in hanging baskets but is also capable of growing on trees and rocks outdoors, with spreading roots that trap moisture and nutrients effectively.
11. Epiphyllum anguliger (Fishbone Cactus)

Its flowers are a beautiful white color, and its leaves are dark, allowing it to form an attractive and impressive waterfall.
13. Disocactus macranthus
This plant is adapted to shady conditions and grows arched shoots that allow it to trail out into the air. It can easily fit itself into nooks and crannies on trees.
Its notched leaves can grow up to 9 feet (3 meters) long.
It produces flashy yellow blooms and makes a beautiful indoor plant in a hanging basket.
14. Lepismium houlletianum (Snowdrop Cactus)
The Lepismium houlletianum has evolved to hang down from tree branches and capture sunlight. Its roots will catch onto any suitable anchor, holding the plant aloft.
It reaches a size of around 4 foot 11 inches (1.5 meters) at the most, and it was given its common name for its delicate, white bell-shaped flowers, which grow along the joints of its stem.
15. Eccremocactus bradei

20. Hylocereus undatus (Dragon-Fruit)
This cactus makes a perfect trailing plant outdoors because it can get quite large and thus needs a good amount of space. Its epiphytic roots will wrap around any suitable surface to support itself.
It can reach over 13 feet (4 meters) in some cases, in both height and spread.
It produces huge beautiful flowers, followed by delicious edible fruits.
What are epiphytic cacti?
An epiphytic cactus is a member of the cactus family that grows with its roots above the soil, usually by attaching itself to another plant or a rock.
Most epiphytic cacti grow in rainforest regions, often in South and Central American regions, and they may look quite different from the desert cacti you are familiar with.
Several different genera of cacti produce epiphytic versions, including Rhipsalis, Weberocereus, Disocactus, Selenicereus, and Hylocereus.
The term epiphytic means that they grow on the surface of another plant, and get nutrients and moisture from the air, rather than drawing them directly from the soil. They usually take up rainwater and collect nutrients from the debris that collects around their roots.
Some cacti grow this way because it suits the environment that they have adapted to. All cacti like to have plenty of oxygen around their roots and good drainage – and this has caused many to grow in sandy conditions, where water can immediately drain away, and there’s plenty of airflow.
For cacti trying to grow where the soil is too heavy and the drainage is too poor, becoming epiphytic is the obvious next step. This gives them access to a good flow of oxygen over their roots and superb drainage.
Being epiphytic is a cactus’s way of recreating its desired conditions in places where the soil is not hospitable for it. That is why most epiphytic cacti grow in rainforest regions.
The majority of cacti that grow as epiphytes do not have sharp spines, and instead, have elongated leaves to maximize their light-gathering capacities. This is more important than defense in the regions where they grow and therefore is the preferred method.
The features of epiphytic cacti can vary, but most have some means of storing water inside their stems, and many also have a basket-like shape so that they can catch debris to provide themselves with nutrients (such as falling leaves).
They have a high level of seed production because there’s a lower chance of their seeds ending up in the right places in the rainforest.
