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.
The USDA Plant Hardiness Zone Map is the standard by which gardeners and growers can determine which plants are most likely to thrive at a location. The map is based on the average annual minimum winter temperature, divided into 10-degree F zones.
