Etymology
The specific epithet "clavata" (pronounced "KLAV-ah-tuh") means "club-shaped" and refers to the shape of the stem segments of this species.
Origin
Rhipsalis clavata is native to Brazil. It grows as an epiphyte on tree branches in Rio de Janeiro and São Paulo.
Description
Rhipsalis clavata is a stunning cactus with long, segmented, highly branched stems that are erect when young but soon hang, often growing over 3.3 feet (1 m) long. The joints (stem segments) are narrowly club-shaped, deep green to brown, and arranged in terminal whorls of 2 to 7. They can reach a length of 1.2 inches (3 cm) and have a few areoles that sometimes bear 1 to 5 white hairs.
The white, bell-shaped flowers appear in spring near the end of the branches. They can measure up to 0.6 inches (1.5 cm) long. The fruits are spherical, white or yellowish, and can grow up to 0.25 inches (0.6 cm) in diameter.
How to Grow and Care for Rhipsalis clavata
Hardiness: USDA hardiness zones 10a to 11b: from 30°F (-1.1°C) to 50°F (10°C).
Rhipsalis do not thrive in direct sunlight. Exposure to the afternoon sun can burn the leaves, turn them yellow, or cause spotting. However, they will not bloom without sufficient sunlight, and their growth can be stunted. These cacti do best with morning sun and afternoon shade.
As Rhipsalis is commonly grown indoors, care must be given to the placement of the plants. They should be kept at least 20 inches (50 cm) away from windows that receive midday or afternoon sun. The glass in the windows can reflect the sun's heat, causing sunburned leaves. Keep in mind that in its native environment, Rhipsalis is accustomed to receiving light filtered through dense, overhanging tree branches. Picturing this environment can help you adjust your lighting accordingly.
Rhipsalis is not a drought-resistant plant, so regular watering is essential. Overwatering, however, can cause weak stems and rotted roots. Using a watering can helps you measure how much water you are providing. The size of the pot relative to the plant, the home's humidity levels, and the type of potting soil used can all affect watering frequency.
