Hildewintera colademononis, or the Monkey Tail cactus, is a stunning cactus that trails downwards. They are native to Bolivia, where they are an epiphytic plant, growing and tailing down rocks.

These cactus need full sun and a well draining soil. Water thoroughly and then allow the soil to dry out completely in between waterings. They are very drought tolerate, especially during the winter months, when you can cut back on watering almost entirely.
