Rhipsalis monacantha - Mistletoe Cactus (syn. Lepismium monacanthum)

Rhipsalis monacantha, known as the Mistletoe Cactus, is a trailing cactus species native to the Atlantic Forest of southeastern Brazil. It is typically found growing on trees in humid, shaded environments where it receives filtered light and benefits from the high ambient moisture of the forest canopy.

The stems are flattened with irregular, slightly toothed edges, and a single central vein, as suggested by the species name. They are green and smooth, branching from the tips to form pendulous chains of segments that can extend to considerable lengths in mature plants.

Small, white flowers emerge along the margins of the segments, often in the warmer months. These are followed by rounded, translucent to whitish berries, which are consumed by birds and aid in dispersal throughout its natural habitat.

Care Tips:

• Light: Prefers bright, indirect light; protect from strong midday sun which may scorch stems.
• Water: Keep evenly moist during the growing season, allowing the surface of the media to dry slightly between waterings; reduce watering in winter.
• Humidity: Benefits from moderate to high humidity; mist occasionally in dry indoor conditions.
• Media: Use a free-draining mix containing fine orchid bark, peat or coir, and perlite.
• Temperature: Best maintained between 15–27°C; protect from frost.
• Fertiliser: Apply a diluted, balanced fertiliser every 4–6 weeks during active growth.
• Repotting: Repot every 2–3 years or when root-bound, ideally in spring.
