(Erica lusitanica lusitanica)
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. Erica arborea is an upright evergreen shrub or small tree with a typical height in the wild of some 7 m (23 ft), especially in Africa, but more typically 1–4 m (3–13 ft) in gardens. It bears dark green needle-like leaves and numerous small honey-scented bell-shaped white flowers. It is a calcifuge, preferring acid soil in an open sunny situation. 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.
