Copperactus

This giant cactus grows up to 177 feet (53.9 meters) tall. It splits partway up the body to form 6 thin stems. Each stem is green, and is covered in brittle brown spines. The mushroom-shaped body is red, and is covered in handfuls of flexible lime spines.

It is very fast growing, taking 4 months to reach maturity. Once mature, and only under the right conditions, several flowers with violet petals that gradient shift to lime on the outer edge. The central disk is light grey grow at the top, reappearing after 6 years, but only when the conditions are right again. The flower head is an uncoordinated mess of up to 40 petals. It has a delicate scent that smells like cotton.

The cactus's skin is delicate, the deep green flesh is leathery, and the copper sap is thin.
