Indigocacti

This small cactus grows up to 5 feet (1.5 meters) tall. It splits randomly along the body to form 2 stiff, pointed stems. Each stem is ashy green, and is covered in sharp spines.

It is steady-growing, taking 5 years to reach maturity. Once mature, and only under the right conditions, a handful of flowers, with petals that are generally indigo; each flower tends to be a variation of this colour, grow at the top, reappearing after 5 years, but only when the conditions are right again. The flower head is an uncoordinated mess of up to 30 petals. It has a mildly strong scent that smells like onion.

The cactus's skin is very thick, the cyan flesh is smooth, and the florescent purple sap is thin.
