Tree Heath (Erica arborea)
Tree heath (Erica arborea) is an evergreen shrub or small tree native to the Mediterranean region, parts of Africa, and southern Europe. It can grow between 6 and 23 feet (2 to 7 meters) tall, with a dense, bushy habit. Its slender branches are covered in tiny, needle-like leaves that give the plant a feathery appearance. During spring, tree heath produces abundant clusters of small, bell-shaped, white or pale pink flowers with a sweet fragrance, attracting pollinators such as bees and butterflies.
The plant thrives in dry, rocky soils and is highly adapted to Mediterranean climates. It prefers full sun but can tolerate some shade. Its deep root system allows it to survive in nutrient-poor conditions and withstand drought. Tree heath regenerates well after fire, making it a common species in fire-prone landscapes.
The plant’s dense wood, known as “briar root,” is highly valued for crafting smoking pipes. In traditional medicine, its flowers and leaves have been used for their diuretic properties. It is also planted as an ornamental shrub in gardens and used for erosion control in degraded lands.
