Jacaranda is a genus of 49 species of flowering plants in the family Bignoniaceae, native to tropical and subtropical regions of the Americas[1] while cultivated around the world.

The species Jacaranda mimosifolia[2] has achieved a cosmopolitan distribution due to introductions, to the extent that it has entered popular culture.

It can be found growing wild in Central America, the Caribbean, Spain, Portugal, southern and northern Africa, China, Australia, Rwanda and Cyprus.

Chambers's Cyclopædia, 1st ed., (1753) as "a name given by some authors to the tree the wood of which is the log-wood, used in dyeing and medicine" and as being of Tupi-Guarani origin,[4][5] by way of Portuguese.

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.

Dilobos, which is believed to be the primitive form, has 31 species and is found primarily in southeastern Brazil including the Paraná River valley.

Several species are widely grown as ornamental plants throughout the subtropical regions of the world, valued for their intense flower displays.
