About

Erica arborea, the tree heath or tree heather, is a species of flowering plant (angiosperms) in the heather family Ericaceae, native to the Mediterranean Basin and Ethiopia, Kenya and Tanzania in East Africa. It is also cultivated as an ornamental.

The wood, known as briar root (French: bruyère, Catalan: bruc, Portuguese: betouro, Spanish: brezo), is extremely hard and heat-resistant, and is used for making smoking pipes. Leaf fossils attributed to this species were described for the Mio-Pleistocene deposit of São Jorge in Madeira Island.

Where it grows

The heather has a disjunct distribution, including both sides of the Mediterranean basin, the western Caucasus, tropical eastern African mountains, and the Arabian Peninsula.

Uses

The wood, known as briar root, 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.
