Silver

This average-sized caudiciform grows up to 5 feet (1.5 meters) tall. The wide stem is lime green, and is covered in lots of rigid silver spines. The crooked, vibrant orange trunk can grow to as much as 5 feet (1.5 meters) in diameter in the middle. Its grey or lime branches are long and thin and start growing halfway up the stem.

The small bunches of smooth-edged, heart-shaped leaves are peach and hazel. They are strong, but detach easily.

It is quick growing, taking 4 months to reach maturity. Once mature, a handful of flowers, with silver petals that gradient shift to blue on the outer edge. The central disk is cyan, grow at the top, reappearing every year. The flower head is made up of many petals; the lower layer of petals are flat, while the upper layers form a tight tube. It has a weak scent that smells like wet dog.

The caudiciform's skin is rock-hard, the crimson flesh is rough, and the lilac sap is thin.
