Indigo

This enormous cactus grows up to 150 feet (45.7 meters) tall. It splits near the top to form 2 perforated stems. Each stem is moss green, and is covered in handfuls of rigid green spines.

It is steady-growing, taking 23 months to reach maturity. Once mature, several flowers with petals that are indigo in the center, purple in the middle and bright red at the edges grow at the top, reappearing once every 8 years. The flower head is made up of 5 petals in raised layers. It has a delicate scent that smells like apple.

The cactus's skin is thin, the cream flesh is rough, and the light brown sap is thin.
