Ferocactus is a genus of cacti native to the deserts of North America, particularly in Mexico and the southwestern United States. These cacti are known for their distinctive barrel shape and prominent ribs, which often feature sharp spines. They can grow to be quite large, with some species reaching heights of up to 10 feet. Ferocactus blooms with vibrant flowers that typically appear in the summer months. The flowers can be red, yellow, or orange and emerge from the top of the cactus. These plants are well-adapted to arid environments and are often used in landscaping due to their striking appearance and low maintenance needs.
