Bronze

This small cactus grows up to 3 feet (91.4 cm) tall. The perforated stem is green, and is covered in brittle light brown spines.

It is steady-growing, taking 12 months to reach maturity. Once mature, and only under the right conditions, several flowers with solid bronze petals decorated with aquamarine dots and a drab red central disk grow at the top, reappearing after 8 years, but only when the conditions are right again. The flower head is largely flat with handfuls of tightly layered round-tipped petals. It has a weak scent that smells like rotten egg.

The cactus's skin is thick, the brilliant blue flesh is slimy, and the brown sap is thin.
