Copperactus

This small cactus grows up to 5 feet (1.5 meters) tall. The narrow stem is yellow-green, and is covered in sharp spines. The spherical body is copper, and is covered in sharp spines.

It is slow growing, taking 27 years to reach maturity. Once mature, a handful of flowers, with petals that are green on the underside and purple on the top, grow at the top, reappearing once every 6 years. The flower head is shaped like a tube with 30 widely spaced, round-tipped petals. It has a delicate scent that smells like vanilla.

The cactus's skin is tough, the red flesh is smooth, and the deep green sap is thin.
