A bizarre herbaceous shrub rarely more than 1.5 m tall with grayish, deeply lobed leaves. The branches and leaf midribs are fiercely armed with orange spines and all parts of the plant are more or less densely furry. The flowers are purple with yellow stamens and are followed by yellow fruits. All parts including the fruits are toxic to humans. Solanum pyracanthos is native to southern Madagascar where it grows in dry, often disturbed habitats. It makes a fascinating ornamental and is easy to grow but should perhaps be avoided in climates where it can escape and become a nuisance.
