Template:Italic title Template:Speciesbox

Erica arborea (tree heath) is a species of flowering plant (angiosperms) in the heather family, Ericaceae. There are disjunct populations in Africa including the Ethiopian Highlands, the mountains of Ruwenzori and the Cameroon Mountains. In Africa it is normally referred to as giant heather. It is native to the maquis shrublands surrounding the Mediterranean Basin north to Bulgaria and west to Portugal and the Canary and Madeira Islands. Naturalised populations occur in south-eastern Australia.<ref name=APNI>Template:APNI</ref>

The wood, known as briar root (French: bruyère), is extremely hard and heat-resistant, and is used for making smoking pipes.

Other tall growing heaths, including the Portugal Heath (Erica lusitanica) and channel heath (Erica canaliculata) may also sometimes be called tree heath.

Uses

Briar pipes on a circular pipe rack

The wood, known as briar root (French: bruyère), is extremely hard, dense and heat-resistant, and is primarily used for making smoking pipes, as it does not affect the aroma of tobacco. The football-sized tubers are harvested at the age of 30 to 60 years. They are cooked for several hours, then dried for several months before they are further processed.

The wood is also used for making jewellery, fountain pens and knife handles.
