verifiedReviewed by the GreenScout Team

Rat Tail Cactus is a unique, trailing succulent with long, slender, snake-like stems covered in soft spines that resemble a rat's tail, making it ideal for hanging baskets. It produces brilliant magenta-pink flowers in spring and prefers bright, indirect light with slightly more water than typical cacti. This cascading cactus can reach 2–4 feet in length over time.

Frequently Asked Questions

Why are the stems on my Cactus Rat Tail turning mushy at the base?

This points to overwatering or poor drainage. Despite tolerating more moisture than desert cacti, it still needs the soil to dry slightly between waterings and excellent drainage to avoid stem and root rot.

Can I trim my Cactus Rat Tail if the trailing stems get too long?

Yes — trim stems after flowering to control length and encourage bushier growth. Cut segments can also be left to callus and propagated as new plants.
