![]() Flowers are followed by elongated, bright yellow or off-white fruits that retain the dried blooms. Flowers, which appear at or near the top of the stems between May and June, may be various shades of yellow or red, depending on the species. pubispinus (Engelm.)

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. They cannot tolerate freezing temperatures for extended periods, which typically cause them to yellow, bleach, then slowly die. In cultivation Ferocactus require full sun, little water, and good drainage. The seeds germinate in areas where water movement occurs or in areas where standing water accumulates for some period of time, and during flash floods, the hooked spines allow the plants to be caught on waterborne debris, uprooted and carried to areas where water tends to accumulate. The "fishhook" spines and the armored web of spines enclosing the cactus body in many species of this genus are adaptations which allow the plant to move to more favorable locations. 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.įerocactus have very shallow root systems and are easily uprooted during flash floods. Like Sclerocactus, Ferocactus typically grow in areas where water flows irregularly or depressions where water can accumulate for short periods of time. 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. They are desert dwellers and can cope with some frost and intense heat. The flowers are pink, yellow, red or purple depending on the species, and the petals sometimes have a stripe of a darker colour. Most of the species are solitary but some, such as Ferocactus robustus and F. The young specimens are columnar but as they grow older ribs form and they take on a barrel form. They are found in the southwestern United States and northwestern Mexico. There are about 30 species included in the genus.
