Turquoise

This small caudiciform grows up to 6 feet (1.8 meters) tall. The finger-like stem is yellow-green, and is covered in handfuls of rigid hazel spines. It has a twisting, round, grey trunk atop a round clump of silky, exposed roots. The branches are thick, gnarled and lime green and olive and trail down to the ground.

The smooth-edged, broad, flat leaves are either slate, or white with deep green lines. They are tough, and do not detach easily.

It is fast growing, taking 3 months to reach maturity. Once mature, a single flower with petals that are generally blue; each flower tends to be a variation of this colour grows at the top, reappearing every year. The flower head is made up of 24 petals; the lower layer of petals are flat, while the upper layers form a tight sphere. It has a weak scent that smells like perfume.

The caudiciform's skin is very thick, the lime flesh is smooth, and the turquoise sap is thin and causes upset stomachs if consumed.
