What does albizzia mean?
An albizzia is any tree or shrub belonging to the genus Albizia, a group of fast-growing leguminous plants native to tropical and subtropical regions of Asia, Africa, and beyond. The best-known species, Albizia julibrissin, is widely called the silk tree or Persian silk tree, prized in gardens and along streets for its graceful, fern-like leaves and its remarkable flowers — fluffy, powder-puff clusters of long silky stamens in pink or white. Albizzias typically have broad, spreading crowns that provide light, dappled shade, which makes them popular ornamental and avenue trees in warm climates. The word derives from the name of Filippo del Albizzi, an eighteenth-century Florentine naturalist who introduced the silk tree to Europe from Constantinople, and the doubled-z spelling is a common variant of the scientific Albizia. Beyond ornament, some species are used in traditional medicine and agroforestry, though a few have become invasive outside their native range.
nounAny of a genus (Albizia) of fast-growing trees and shrubs of the legume family, native chiefly to tropical and subtropical Asia and Africa, bearing feathery bipinnate leaves and clusters of silky, showy flowers.
- A tree or shrub of the legume genus Albizia, valued ornamentally for its feathery foliage and silky flower clusters, especially the silk tree (Albizia julibrissin).
"The albizzia in the courtyard burst into pink silk-like blooms each midsummer."
"A mature albizzia shaded the entire terrace with its umbrella of fern-like leaves."
"In traditional medicine, the dried bark of the albizzia has long been used in parts of Asia."
The regular English plural 'albizzias' is standard; in botanical contexts the Latinised genus name Albizia may stand unchanged.
"The avenue was lined with flowering albizzias."
The albizzia is named after an 18th-century Italian naturalist, Filippo del Albizzi, who brought the tree from Constantinople to Florence — so every silk tree in the world carries a Florentine family name.

Etymology of albizzia
The word albizzia comes from New Latin Albizia, the botanical genus name coined in honour of Filippo del Albizzi, an eighteenth-century Florentine nobleman and naturalist who introduced the silk tree from Constantinople to cultivation in Europe. The surname Albizzi itself is that of a prominent medieval Florentine family. The variant spelling with a double z arose early and remains common in general dictionaries, while the scientific literature standardised on Albizia with a single z.
How albizzia is actually used
The spelling 'albizzia' is a variant of the standard scientific spelling 'Albizia'; both are accepted in general dictionaries, with the doubled-z form common in older and British texts. The word is botanical and somewhat formal, appearing mainly in gardening, forestry, and scientific writing.
Easily confused with albizzia
An acacia is a different genus of often thorny leguminous trees, whereas an albizzia is thornless with silky, thread-like flowers and feathery leaves.
Mimosa is a separate genus of sensitive plants, though 'mimosa' is loosely and incorrectly used as a common name for some albizzias such as the silk tree.
