Aquamarine

This colossal cactus grows up to 140 feet (42.7 meters) tall. The sickle shaped stem is lime green, and is covered in hundreds of rigid aquamarine spines. The spherical body is pink-red, and is covered in many flexible slate spines.

It is steady-growing, taking 4 years to reach maturity. Once mature, and only under the right conditions, several flowers with petals that are bronze on the edges and lilac at the center grow at the top, reappearing after 6 years, but only when the conditions are right again. The flower head is shaped like a tube made up of many widely spaced, round-tipped petals. It has an intense scent that smells like wet dog.

The cactus's skin is delicate, the yellow flesh is waxy, and the faded blue sap is thin.
