Albizia julibrissin

Features and care

The Albizia julibrissin, popularly known as the silk tree or Constantinople acacia, is a deciduous tree native to Asia (from Iran to China and Korea) that stands out for its wide, umbrella-like crown and its striking, feathery, bright pink flowers, which appear mainly in summer and give off a soft aroma.

Its bipinnate, feathery, and delicate foliage, along with its rapid growth, makes it a highly valued choice for both shade trees in gardens and as a standalone specimen or for urban street plantings. It tolerates drought well once established and adapts to a wide variety of soils, provided they are well-drained.

At Ornacom we cultivate each specimen directly, guaranteeing a balanced size and abundant flowering from the first years of planting.
