Silverstorm

This modest-sized cactus grows up to 58 feet (17.7 meters) tall. The wide stem is silver, and is covered in brittle brilliant green spines.

It is steady-growing, taking 15 months to reach maturity. Once mature, several flowers with grey petals that gradient shift to grey on the outer edge. The central disk is red grow at the top, reappearing once every 10 years. The flower head is largely flat with 4 raised round-tipped petals. It has a strong scent that smells like candle wax.

The cactus's skin is thin, the dark brown flesh is rough, and the purple sap is thin.
