Luminara Succulent

This average-sized leaf succulent grows up to 20 feet (6.1 meters) tall. The thin stem is emerald, and is covered in thick bunches of rigid cream spines. The stumpy leaves are slate and muted yellow. Handfuls of them grow on thick, indigo branches that are short stubs. The leaves are delicate, but easily come away when pulled.

It is steady-growing, taking 7 months to reach maturity. Once mature, a single flower with solid bronze petals decorated with vibrant blue lines and a cream central disk grows at the top, reappearing once every 10 years. The flower head is shaped like a cup with 49 widely spaced, round-tipped petals. It has a weak scent that smells like rainy days.

The leaf succulent's skin is very thick, the olive flesh is slimy, and the purple sap is thin and can kill if consumed.
