Lime Green Cactus

This colossal cactus grows up to 137 feet (41.8 meters) tall. It splits near the top to form 3 asymmetrical stems. Each stem is lime green, and is covered in hundreds of fine, hazel, hair-like spines.

It is steady-growing, taking 7 months to reach maturity. Once mature, a single flower with deep blue petals and a bright purple central disk grows at the top, reappearing once every 3 years. The flower head is shaped like a cup made up of 10 tightly layered, round-tipped petals. It has an intensely strong scent that smells like bleach.

The cactus's skin is nearly impenetrable, the brown flesh is rough, and the aquamarine sap is thin.
