About

Jacaranda is a genus of 49 species of flowering plants in the family Bignoniaceae, native to tropical and subtropical regions of the Americas and cultivated around the world. The generic name is also used as the common name.

The species Jacaranda mimosifolia has achieved a cosmopolitan distribution due to introductions, to the extent that it has entered popular culture. It can be found growing as an environmental weed in Central America, the Caribbean, Spain, Portugal, southern and northern Africa, China, Australia, Rwanda and Cyprus.

How to grow it

Jacaranda can be propagated from grafting, cuttings, and seeds, though plants grown from seeds take a long time to bloom. Jacaranda grows in well-drained soil and tolerates drought and brief spells of frost and freeze.

This genus thrives in full sun and sandy soils, which explains their abundance in warmer climates. Mature plants can survive in colder climates down to −7 °C (19 °F); however, they may not bloom as profusely. Younger plants are more fragile and may not survive in colder climates when temperatures drop below freezing.

Uses

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.
