Silverbell

This big cactus grows up to 84 feet (25.6 meters) tall. It splits partway up the body to form 6 thin stems. Each stem is gray-green, and is covered in large amounts of fine, pastel yellow, hair-like spines. The spherical body is silver, and is covered in sharp spines.

It is very slow growing, taking 13 years to reach maturity. Once mature, and only under the right conditions, a single flower with alternating petals of slate and pink, with a pale purple central disk grows at the top, reappearing after 7 years, but only when the conditions are right again. The flower head is an uncoordinated mess of up to 20 curved petals. It has an overpowering scent that smells like soap.

The cactus's skin is thick, the dark grey flesh is rough, and the indigo sap is thin.
