An epiphytic tropical cactus (Rhipsalis means wicker work in Greek). If you want to feed it, give it a weak cactus fertilizer every 4 weeks through the summer.
Water lots in the summer, allow to dry out between watering. Water a little in the winter. Don’t let it sit in water. Repot in free draining compost.
Bright spot, not in direct sunlight (morning and evening sun is fine, not midday sun).
Keep above 15 degrees C.
