Jacaranda (pronounced [ʒa.ka.ˈran.da], [ha.ka.ˈran.da], or [ˌdʒæk.ə.ˈran.də]) is a genus of 49 species of flowering plants in the family Bignoniaceae, native to tropical and subtropical regions of South and Central America, Mexico, and the Caribbean. The genus name is also used as the common name.
The species are shrubs to large trees ranging in size from 2-30 m tall. The leaves are bipinnate in most species, pinnate or simple in a few species. The flowers are produced in conspicuous large panicles, each flower with a five-lobed blue to purple-blue corolla; a few species have white flowers. The fruit is an oblong to oval flattened capsule containing numerous slender seeds. The genus differs from other genera in the Bignoniaceae in having a staminode that is longer than the stamens, tricolpate pollen, and a chromosome number of 18.
The genus is divided into two sections, sect. Jacaranda (syn. sect. Monolobos, an invalid name as it includes the type species of the genus, J. caerulea) and sect. Dilobos DC., based on the number of thecae on the anthers. Sect. Jacaranda (which includes Blue Jacarandas) has 18 species and is found primarily in western South America, Central America, Mexico, and the Caribbean. Sect. Dilobos, which is believed to be the primitive form, has 31 species and is found primarily in southeastern Brazil including the Paraná River valley. The anatomy of the wood in the two sections also differs. Although usually treated in sect. Jacaranda, J. copaia differs somewhat from all other members of the genus, and may be intermediate between the two sections (Dos Santos & Miller 1997).
Several species are widely grown as ornamental plants throughout the subtropical regions of the world, valued for their intense flower displays. The most often seen is the Blue Jacaranda Jacaranda mimosifolia (syn. J. acutifolia hort. non Bonpl.). Other members of the genus are also commercially important; for example the Copaia (Jacaranda copaia) is important for its timber because of its exceptionally long bole.
