This genus contains a few species of dwarf evergreen shrubs with deep-green leathery leaves, small white flowers, and masses of variously coloured berries in autumn and winter. They are excellent plants for massing in beds, on banks, or for rock gardens. They like a compost of sand, peat or leaf mould, and a little loam, and are increased by layering and from seeds. The best kind is P. mucronata, the Prickly Heath, a wiry shrub, 2-3 ft. high, from the Straits of Magellan. There are several varieties.
