Mistletoe cacti are increasingly popular indoor plants. Their unique aesthetic, featuring cascades of interesting foliage, offers a distinct visual appeal that can transform any living space. Their adaptability to various indoor conditions also contributes to their growing appeal.
What are Mistletoe Cacti
Mistletoe cacti belong to the Rhipsalis genus. Unlike the desert cacti often associated with arid environments, Rhipsalis species are epiphytic, meaning they naturally grow on other plants, typically trees, in tropical rainforests without drawing nutrients from their hosts. This growth habit allows them to thrive in the filtered light and humid conditions found beneath dense forest canopies.
These plants are characterized by their leafless, segmented stems that can be cylindrical, angular, or flattened. Most Rhipsalis species lack the prominent spines found on many desert cacti. They produce small, inconspicuous flowers, typically white or greenish-white, followed by berry-like fruits that resemble mistletoe berries, hence their common name.
Common Mistletoe Cactus Varieties
Rhipsalis baccifera
Rhipsalis baccifera, known as the common Mistletoe Cactus, features long, slender, pendulous stems that can grow several feet, resembling green spaghetti. Its stems are initially cylindrical, sometimes becoming slightly flattened, and produce small, funnel-shaped white or greenish-white flowers and translucent white or pale pink berries. This species is notable as the only cactus with a natural occurrence outside the Americas, found in parts of Africa and Sri Lanka.
Rhipsalis cereuscula
Rhipsalis cereuscula, called the Rice Cactus or Coral Cactus, has a bushy, compact form, with stems that cascade as they mature. It is identified by its tiny, cylindrical stems resembling grains of rice. Small creamy white flowers, sometimes tinged with pink, emerge from stem tips, followed by tiny white berries.
Rhipsalis pilocarpa
Rhipsalis pilocarpa features stems and fruits densely covered by fine, white bristles, giving it a fuzzy or snowy appearance. Its flowers are typically small and white.
Rhipsalis paradoxa
Rhipsalis paradoxa, known as the Chain Cactus, has long, branching stems with three-angled ridges that alternate along their length, creating interconnected segments. This variety produces small white or cream flowers along the edges of its stems, often followed by red or pink berries.
General Care Guidelines
Mistletoe cacti thrive in bright, indirect light, mimicking their natural habitat where sunlight is filtered through tree canopies. While they can tolerate lower light conditions, consistent direct afternoon sun can scorch their stems and inhibit flowering. Placing them a few feet away from a bright window or in an east-facing location is often ideal.
Unlike desert cacti, Rhipsalis prefer consistent moisture. The soil should be allowed to dry out slightly between waterings, typically when the top inch or two feels dry to the touch. Overwatering can lead to root rot, so ensuring good drainage is important. During cooler months, watering frequency should be reduced as the plant’s growth slows.
A well-draining, airy soil mix is suitable for these epiphytic cacti. A blend designed for cacti and succulents, often amended with organic materials like shredded bark, perlite, or sphagnum moss, improves aeration and drainage. They appreciate warmer temperatures (16°C to 27°C / 60°F to 80°F) and higher humidity (50-70%). Misting or using a humidity tray can provide necessary moisture in drier indoor environments.
Light fertilization during the active growing season, spring and summer, can support healthy development. A balanced, diluted liquid houseplant fertilizer or a cacti-specific feed applied monthly is generally sufficient. Fertilization should be avoided during the dormant winter months.
Choosing the Right Mistletoe Cactus
When selecting a mistletoe cactus, consider your home’s light conditions; varieties preferring dappled light thrive in bright, indirect exposure. Consider the desired growth habit: some Rhipsalis offer long, trailing stems for hanging baskets, while others are more compact or bushy. Personal aesthetic preference, such as unique stem shapes or bristles, can also guide your choice.
