Dog Tail Cactus

Selenicereus testudo

Dog Tail Cactus Plant Features

Dog tail cactus is an interesting and exotic houseplant with cylindrical leaves dotted in clusters of small spines. The effect is attractive and unique. Because dog tail cactus trails as it grows, it's a fine candidate for hanging baskets in front of a sunny window. Use it to crate a fountain-like effect from the pot!

Note: You may also see this plant offered under the name Deamia testudo.

Dog Tail Cactus Growing Instructions

Grow dog tail cactus in a bright spot. If it gets enough light, it produces pretty pink blooms that have an exotic, orchid-like look to them.

This exotic houseplant is a type of cactus, so water it when the soil dries out. Dog tail cactus will rot if you water it too much. 

Dog tail cactus is not intended to be consumed by humans or animals.
