Bronze

This average-sized caudiciform grows up to 23 feet (7.0 meters) tall. The fan-like stem is orange-yellow, and is covered in dozens of rigid bronze spines. The stocky, black trunk can grow to as much as 23 feet (7.0 meters) in diameter. Its copper branches are long, thin and wispy.

The tattered-edged, thin leaves are light grey at the bottom and gold with light brown splotches at the top. They are light, and are very difficult to pull away.

It is very slow growing, taking 36 years to reach maturity. Once mature, and only under the right conditions, a handful of flowers, with petals that are generally yellow; each flower tends to be a variation of this colour, grow at the top, reappearing after 9 years, but only when the conditions are right again. The flower head is made up of several petals in raised layers. It has a weak scent that smells like soap.

The caudiciform's skin is very thick, the bright blue flesh is smooth, and the olive sap is thin.
