Copper

This modest-sized leaf succulent grows up to 16 feet (4.9 meters) tall. The finger-like stem is copper, and is dotted with small lime spines. The rounded-edged, thin leaves are green and silver. Sparse amounts of them grow from the base in a spiral pattern. The leaves are durable, and detach easily.

It is slow growing, taking 19 years to reach maturity. Once mature, several flowers with petals that are red on the underside and caramel on the top grow at the top, reappearing once every 10 years. The flower head is made up of 10 petals in raised layers. It has an overpowering scent that smells like coffee.

The leaf succulent's skin is delicate, the yellow flesh is leathery, and the vibrant green sap is thin and causes diarrhea if consumed.
