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. These cacti are true desert dwellers, surviving in areas where they can get some frost and intense heat. They are often called “Fishhook cacti” due to the hooked spines that many of the genus have. Ferocactus are great plant for beginners with their very easy care requirements.
