Mistletoe Cactus

Rhipsalis baccifera has the most extraordinary geographic distribution of any cactus.

• In the Americas: found from southern Florida and Mexico through Central America, the Caribbean, and throughout tropical South America
• In the Old World: occurs in tropical Africa (from Guinea to Kenya and south to South Africa), Madagascar, Comoros, Mauritius, Réunion, Seychelles, and Sri Lanka
• Grows as an epiphyte on tree trunks and branches in tropical and subtropical forests, from sea level to approximately 1,500 meters
• Also occasionally grows as a lithophyte on rocks or mossy boulders
• The species was first described by the Swedish botanist Carl Linnaeus in 1753 as Cassytha baccifera
• How it crossed the Atlantic remains debated — leading theories include dispersal by migratory birds carrying seeds in their digestive tracts, or rafting on floating vegetation
• Molecular evidence suggests the Old World colonization occurred relatively recently, approximately 2 to 5 million years ago

A highly variable, pendulous, epiphytic or lithophytic cactus with slender, branching stems.

Stems:
• Slender, cylindrical, typically 3 to 6 mm in diameter
• Segments are elongated, branched, and freely pendant, forming cascading masses up to 1 to 3 meters long
• Bright green to dark green, smooth, without ribs or tubercles
• Areoles: minute, bearing few or no spines, sometimes with a few white bristles when young
• Young stems may appear slightly angular but become cylindrical with age

Flowers:
• Very small, approximately 8 to 12 mm in diameter
• Whitish to creamy yellow or pale green
• Bell-shaped to rotate, often appearing along the stems rather than just at the tips
• Bloom period varies across its vast range, generally in spring to summer

Fruit:
• Small, globose berries, 5 to 8 mm in diameter
• White, translucent, or pale pinkish when ripe
• Resemble mistletoe berries — hence the common name
• Each berry contains 1 to 4 small black seeds in a sticky pulp

An epiphyte of tropical and subtropical forest canopies.

• Grows in the crotches of tree branches, on mossy trunks, and on shaded cliff faces
• Tolerates a wide range of light conditions from deep shade to bright filtered light
• Absorbs moisture and nutrients from rain, humidity, and organic debris that accumulates around its roots
• Flowers are pollinated by insects, particularly small bees and flies
• Berries are consumed by birds, which disperse seeds to new host trees — this bird-mediated dispersal likely enabled its trans-Atlantic colonization
• Plays a role in the canopy ecosystem by providing habitat for insects and amphibians
• Can form dense hanging curtains on large trees in humid forests

Light:
• Prefers bright, indirect or filtered light — mimic the dappled shade of a forest canopy
• Avoid direct midday sun, which can scorch the stems
• Tolerates lower light conditions better than most cacti

Soil:
• Use a loose, airy, well-draining epiphytic mix
• Combine orchid bark, perlite, and a small amount of peat or coco coir
• Must never remain waterlogged; the roots need excellent aeration

Water:
• Water regularly during the growing season, keeping the soil lightly moist but not soggy
• Mist the stems occasionally to maintain humidity
• Reduce watering slightly in winter but do not allow the plant to shrivel completely
• Unlike desert cacti, Rhipsalis should never dry out completely for extended periods

Temperature:
• Prefers warm conditions, 18 to 25°C year-round
• Not frost-tolerant; protect from temperatures below 5°C
• Appreciates high humidity, similar to its native tropical habitat

Propagation:
• Very easy from stem cuttings
• Simply place cuttings on moist soil or in a hanging basket
• Rooting typically occurs within 2 to 4 weeks
• Also propagates from seed, though this is less common
