Living rock

These plants are short and wide, typically just 6 inches tall but up to 12 inches wide. They are a dull, greenish grey color, resembling a rock. The spines are downward curving like a hook, but they do not completely cover the surface. This is perhaps one of the most spectacular flowers found in the desert. They are found on the very top center of the cactus, showy and pink while appearing throughout the summer months.
