Ferocactus is a genus of about 30 large, barrel-shaped cacti from the southwestern United States and northwestern Mexico, with large spines and small pink, yellow, red or purple flowers. The key to growing them is full sun, very little water and fast-draining soil.

About

Ferocactus is a genus of large barrel-shaped cacti, mostly with large spines and small flowers. There are about 30 species included in the genus. They are found in the southwestern United States and northwestern Mexico.

How to grow it

In cultivation Ferocactus require full sun, little water, and good drainage. They are popular as houseplants. They cannot tolerate freezing temperatures for extended periods, which typically cause them to yellow, bleach, then slowly die. Propagation is usually from seeds, but clustering species such as Ferocactus robustus and F. glaucescens can be propagated by removing a rooted offset and planting it.

Where it grows

They are desert dwellers and can cope with some frost and intense heat. The typical habitat is hot and very arid, and the plants have adapted to exploit water movement to concentrate their biomass in areas where water is likely to be present. Like Sclerocactus, Ferocactus typically grow in areas where water flows irregularly or depressions where water can accumulate for short periods of time. They are most often found growing along arroyos (washes) where their seeds have been subjected to scarification due to water movement, but they oddly also tend to grow along ridges in spots where depressions have formed and can hold water for some period of time.
