Rhipsalis sulcata

DESCRIPTION
Rhipsalis sulcata, commonly known as the Grooved Mistletoe Cactus, is a charming epiphytic cactus from the Cactaceae family. Native to the rainforests of Brazil, this plant grows naturally on tree branches where it enjoys dappled light and high humidity. Unlike desert cacti, Rhipsalis sulcata has no spines and features cascading stems that make it perfect for hanging displays. This is a beginner-friendly plant that adapts well to typical indoor conditions. Fun fact: Rhipsalis is the only cactus genus naturally found outside the Americas, with some species occurring in Africa and Madagascar. 🌿
FOLIAGE AND GROWTH HABIT
This cactus has a gracefully trailing growth habit with slender, cylindrical stems that branch out in all directions. The stems are bright green and feature distinctive grooves or ribs running lengthwise along each segment, which is where the species name "sulcata" comes from. The texture is smooth and slightly succulent, storing water within the stems. As the plant matures, the cascading stems can reach lengths of 30 to 60 centimetres, creating a waterfall effect that looks stunning in hanging planters.
FLOWER DETAILS
Rhipsalis sulcata produces small, delicate flowers that appear along the stems, typically in late winter to early spring. The blooms are white to pale cream in colour with a simple, star-shaped form consisting of several narrow petals. They carry a subtle, sweet fragrance that's most noticeable in the morning. While the flowers are small and understated compared to other cacti, they add a lovely touch of elegance to the cascading foliage. To encourage flowering, provide bright indirect light and allow the plant to experience slightly cooler temperatures during winter months, around 15 to 18 degrees Celsius. With proper care, established plants will bloom reliably each year.
CARE INSTRUCTIONS
🌞 Light: Bright indirect light is ideal, though it tolerates partial shade. Avoid direct sun which can scorch the stems. Aim for 4 to 6 hours of filtered light daily.
💧 Water: Water when the top 2 to 3 centimetres of soil feel dry. In spring and summer, water every 7 to 10 days. Reduce to every 2 to 3 weeks in winter. Bottom watering or thorough soaking works best, allowing excess to drain completely.
🌡️ Humidity: Prefers higher humidity between 50 to 70 percent. Mist occasionally or place near a humidifier if your home is dry.
🪴 Soil: Use a well-draining cactus or succulent mix, or blend regular potting soil with perlite and orchid bark for aeration.
🏺 Potting: Choose a shallow hanging basket or pot with drainage holes. Terracotta or plastic both work well. Repot every 2 to 3 years in spring when roots become crowded.
🌱 Growth rate: Moderate growth. Expect 10 to 15 centimetres of new growth in 6 months under good conditions. Over a year, stems can extend 20 to 30 centimetres. Mature specimens reach 60 centimetres or more in length.
👩‍🌾 Fertilizing: Feed monthly during spring and summer with a diluted balanced liquid fertilizer or cactus formula at half strength. Skip fertilizing in autumn and winter.
🐾 Pet friendly: Yes, Rhipsalis sulcata is non-toxic to cats and dogs, making it a safe choice for homes with pets.
WHERE TO PUT IT
Rhipsalis sulcata thrives in bathrooms where humidity is naturally higher, or in bright living rooms and bedrooms with indirect light from east or west-facing windows. It looks spectacular in hanging planters near windows or on high shelves where the trailing stems can cascade freely. Kitchens with good light also work well. Avoid placing it in dark corners, near heating vents, or in spots with intense direct sunlight, as these conditions will stress the plant and cause the stems to yellow or dry out.
