Silverfern

This huge leaf succulent grows up to 178 feet (54.3 meters) tall. The slender, pointed stem is pink-red, and is covered in lots of flexible silver spines. The toothed-edged, very narrow and elongated leaves are amber at the bottom and aquamarine with magenta streaks at the top. Large amounts of them grow from the base in alternating pairs. The leaves are durable, but detach easily.

It is slow growing, taking 8 years to reach maturity. Once mature, and only under the right conditions, a handful of flowers, with petals that are sky blue on the edges and lilac at the center, grow at the top, reappearing after 4 years, but only when the conditions are right again. The flower head is made up of several petals; the lower layer of petals are flat, while the upper layers form a tight cup. It has a delicate scent that smells like roses.

The leaf succulent's skin is thin, the purple flesh is leathery, and the blue sap is thin and causes upset stomachs if consumed.
