About Mexican lime cactus
Ferocactus pilosus, commonly known as Lime Barrel Cactus, is a robust, solitary columnar cactus that can reach impressive heights. It is distinguished by its bright red or orange spines densely covering its stem, creating a spectacular visual effect. It is ideal for desert gardens, rockeries, or as a striking specimen in large pots, adding an exotic and architectural touch.
Native range
Mexico (states of Coahuila, Nuevo León, San Luis Potosí, Tamaulipas, and Zacatecas)
Care tips
It requires direct sun exposure to fully develop its spines and maintain its compact form. Watering should be scarce, allowing the substrate to dry out completely between waterings, and almost none in winter to prevent rot. Use a very well-drained substrate, specific for cacti and succulents. A common mistake is overwatering, which is the main cause of death in this species.
