Ferocactus

From the Latin ferus, wild, and cactus; the plants are very spiny (Cactaceae). Hedgehog cactus. A genus of greenhouse cacti, globular plants, becoming columnar with age, with thick prominent ribs armed with strong spines, some hooked.

Species cultivated

F. latispinus, stem globular, depressed at top, the areoles with a group of strong, curved spines, flowers funnel-shaped, carmine-red, Mexico. F. pringlei, sometimes branches from base, flowers red-orange, yellow inside, central Mexico. F. wislizenii, globular when young, growing to 6 feet high in its native habitat, 15-20 ribs, spines thick and strong, some hooked, flowers reddish-yellow, Texas.

Cultivation

These cacti thrive in a compost consisting of a regular potting compost with a sixth part of extra sand grit or broken brick. They should be given a sunny position in the greenhouse. Repot every two or three years in March. Water from March to September, only when the soil has completely dried out. Temperature: 65-75°F (18-24°C), March to September, 40 °F (4°C), September to March, when the soil must be kept dry.

P Ferocactus ropagation is by seed sown in pans of reliable seed compost, when a temperature of 70°F (21°C), can be maintained; just cover the seed and keep moist and shaded. These plants do not normally make offsets unless the top is cut off. This can be dried and rooted, the base will then produce offsets.
