'''''Jacaranda''''' is a genus of 49 species of flowering plants in the family Bignoniaceae, native to tropical and subtropical regions of the Americas<ref name="Gentry1992">{{cite journal | title=Bignoniaceae: Part II (Tribe Tecomeae) | author=Gentry, A.

The generic name is also used as the common name.
The species ''Jacaranda mimosifolia''<ref>{{cite web |title=Jacaranda mimosifolia D.Don |url=https://powo.science.kew.org/taxon/urn:lsid:ipni.org:names:130936-2 |website=Plants of theWorld Online}}</ref> 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.
==Etymology== The name is of South American (more specifically Tupi–Guarani) origin.<ref>{{cite web|url=http://mediambient.itineraris.bcn.cat/en/node/259/365|title=Jacaranda mimosifolia - Parcs i Jardins - Itineraris|work=bcn.cat}}</ref><ref>{{cite book|author-link=Teodoro Fernandes Sampaio|first=Teodoro|last= Sampaio|url=https://bdor.sibi.ufrj.br/handle/doc/429|title= O tupi na geografia nacional|page=263}}</ref><ref>{{cite web|url=https://www.infopedia.pt/dicionarios/lingua-portuguesa/jacaranda |title=jacaranda|website=Dicionário Infopédia da Língua Portuguesa|publisher=Porto Editora}}</ref> The word ''jacaranda'' was described in ''A supplement to Mr. 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,<ref>''Oxford English Dictionary'' 2nd Ed.

==Description== {{expand section |date=April 2026}}
The species are shrubs to large trees ranging in size from {{convert|20|to|30|m|ft|abbr=on}} tall. Most of its species have bipinnate leaves, leaves on the rest are pinnate or simple. Their wood tissue has narrow vessels and splayed parenchyma.<ref name="PotNtJ">{{cite journal |last1=Ragsac |first1=Audrey C. |last2=Farias‐Singer |first2=Rosana |last3=Freitas |first3=Loreta B. |last4=Lohmann |first4=Lúcia G. |last5=Olmstead |first5=Richard G. |date=December 2019 |title=Phylogeny of the Neotropical tribe Jacarandeae (Bignoniaceae) |journal=American Journal of Botany |volume=106 |issue=12 |pages=1589–1601 |doi=10.1002/ajb2.1399}}</ref>{{rp|1590}}
Jacaranda flowers are produced in conspicuous large panicles, each flower with a five-lobed blue to purple-blue corolla; a few species have white flowers. Flowers of this genus's species differ from other genera in their family by having staminodes longer than the stamens that not only make the flowers more visually interesting to pollinators like orchid bees, but also have glandular trichomes secreting plant metabolites that attract those bees.<ref name="PotNtJ"/>{{rp|1590}} Jacaranda flowers also have tricolpate pollen, and a chromosome number of 18.{{cn |date=April 2026}}
The fruit is an oblong to oval flattened capsule containing numerous slender seeds, this trait is shared with other species in the Jacarandeae tribe.<ref name="PotNtJ"/>{{rp|1590}}
==Taxonomy== The genus is divided into two sections, sect. ''Monolobos'' and sect. ''Dilobos'' DC., based on the number of thecae on the anthers. Sect. ''Monolobos'' 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. ''Monolobos'', ''J. copaia'' differs somewhat from all other members of the genus and may be intermediate between the two sections (Dos Santos & Miller 1997).

==Cultivation== left|thumb|162x162px|Jacaranda seedling 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.<ref name="jacaranda">{{cite web|url=http://www.thelovelyplants.com/jacaranda-tree/|title=Jacaranda Tree|work=The Lovely Plants|access-date=2010-10-05|archive-date=2015-12-25|archive-url=https://web.archive.org/web/20151225190539/http://www.thelovelyplants.com/jacaranda-tree/|url-status=dead}}</ref><ref>{{cite web |url=https://www.wikilawn.com/drought-tolerant-plants/jacaranda-tree/ |title=Jacaranda Tree |website=www.wikilawn.com |access-date=13 May 2020 |archive-date=2 August 2020 |archive-url=https://web.archive.org/web/20200802024502/https://www.wikilawn.com/drought-tolerant-plants/jacaranda-tree/ |url-status=dead }}</ref>
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 {{convert|-7|C|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.
