Super interesting epiphyllum / succulent vine. A paradox because each joint reverses to make the most unique "chain like cactus" - aka chain cactus.
This is an easy care house plant or patio plant. Grows well in bright indirect sunlight, water moderately, allow to dry out before watering again.
You are buying a rooting cutting which is already branching. Roots easily and you can quickly propogate to make up a cool hanging basket full of "dreadlocks". If you don't want to wait, buy 2-3 and start to create that hanging basket now.
