Description
Rhipsalis cereuscula is a shrubby cactus with light green stems crowned with clusters of tiny rice-shaped joints. The stems are up to 3 feet (90 cm) long, erect at first, becoming pendant as they grow.
The flowers are greenish-white, often tinged with pink, borne from the terminal areoles and followed by tiny white berries. They are bell-shaped, up to 0.6 inches (1.5 cm) long, and up to 0.8 inches (2 cm) in diameter.
Hardiness
USDA hardiness zones 10a to 11b: from 30 °F (−1.1 °C) to 50 °F (+10 °C).
How to Grow and Care
Rhipsalis do not thrive in direct sunlight. Exposure to the afternoon sun can burn the leaves, turn them yellow or lead to spotting. However, they will not bloom without sufficient sunlight, and their growth can be stunted. Therefore, these cacti do best with morning sun and full shade in the afternoon.
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) from windows that receive midday or afternoon sun. The glass in the windows can multiply the heat from the sun's rays, 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 help you measure the amount of water you are providing. The pot's size compared to the plant's size, the humidity levels in the home, and the type of potting soil used can all affect the watering frequency.
