Pernettya mucronata; also known as prickly heath,[1] chaura, or murtillo) is a species of flowering plant in the family Ericaceae, native to southern Argentina and Chile.

[2] In volcanic areas of southern Chile Gaultheria mucronata is one of the dominant plant species above the tree line.

It is a compact, bushy, evergreen shrub with glossy green leaves and solitary white flowers in spring, followed in autumn by showy globose berries up to 1.5 cm (0.59 in) in diameter, in shades from deep plum purple through pink to pure white.

It is dioecious, meaning that both male and female plants must be grown together in order to produce fruit.

[8] The Latin specific epithet mucronata means “prickly”, referring to the foliage.
