Cyanactus

This massive cactus grows up to 111 feet (33.8 meters) tall. It splits near the top to form 2 wide stems. Each stem is beige and blood red, and is covered in thick sheets of flexible lilac spines.

It is steady-growing, taking 4 years to reach maturity. Once mature, several flowers with each petal a slightly different shade of white grow at the top, reappearing once every 10 years. The flower head is an uncoordinated mess of up to 20 petals. It has a fairly strong scent that smells like mango.

The cactus's skin is very thick, the cyan flesh is smooth, and the pink sap is thin and has hallucinogenic properties.
