Consolea rubescens - Growth, Features and Care Guide

Consolea rubescens, commonly known as the Road Kill Cactus, is a striking cactus native to the Caribbean, including Puerto Rico, the Lesser Antilles, and the Virgin Islands. Often sold under its synonym Opuntia rubescens or mistakenly labeled as "Opuntia consolea", it stands out with minimal spines and a sculptural appearance.

Known for its flattened, paddle-like pads forming a tree-like structure, this species develops intriguing textures, earning its nickname "Road Kill Cactus." In spring, it produces bright orange flowers, sometimes followed by ornamental fruits. Outdoors, it can reach up to 6 meters, but indoors, it stays under 1 meter.
