Etymology
The specific epithet "elliptica (pronounced ee-LIP-tih-kuh)" means "elliptical" and refers to the shape of the segments of the branches of this species.
Origin
Rhipsalis elliptica is native to Brazil. It grows as an epiphyte in the southern and southeastern portions of the Atlantic Forest.
Description
Rhipsalis elliptica is a much-branched cactus with pendent, segmented, dark green branches often tinged magenta to purple. The stems can grow up to 6.6 feet (2 m) long. The basal branches are usually 3-winged and can reach 14 inches (35 cm) in length. The branch segments are mostly flattened, more or less elliptical, with round-toothed margins, measuring up to 7.2 inches (18 cm) in length and 3.4 inches (8.5 cm) in width.
The flowers are small with yellowish, widely spreading petals, numerous white filaments, and white stigma lobes. They appear in late winter and early spring, generally solitary or sometimes 2 or 3 at an areole. The fruits are reddish, slightly longer than broad, and about 0.3 inches (0.7 cm) long.
How to Grow and Care for Rhipsalis elliptica
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 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 afternoon shade.
As Rhipsalis is commonly grown indoors, care must be taken with plant placement. 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 drought-resistant, 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 pot's size relative to the plant, the home's humidity levels, and the type of potting soil used can all affect watering frequency.
