Jacaranda mimosifolia is a sub-tropical tree native to south-central South America that has been widely planted elsewhere because of its attractive and long-lasting violet-colored flowers. It is also known as the jacaranda, blue jacaranda, black poui, or fern tree.
Common Name: JACARANDA Habit: [Shrub] tree. Species In Genus: 50 species: Central America (except Mexico), South America, Caribbean.Etymology: (Brazilian common name) Reference: Jones et al. 2005 Amer Naturalist 166:543--555
Common Name: Jacaranda. Scientific Name: Jacaranda mimosifolia. Family: Bignoniaceae. Identification. Habit:. Jacarandas grow more wide than tall. Average heights of mature trees range from 7 to 15 meters while the spread ranges from 7 to 20 meters wide (Gilman & Watson, 1993).
Nov 05, 2017 · Although known by several vernacular names, jacaranda is commonly used. However, in the timber trade, the name 'jacaranda' is not associated with J. mimosifolia, but with Dalbergia nigra instead. Furthermore, other vernacular names include Brazilian rose wood and green ebony, that both add to possible confusion with other species.

Locations within which Jacaranda mimosifolia is naturalisedinclude the warmer parts of eastern Australia, southern Africa, Hawaii, south-eastern USA and outside its native range in southern South America.
Jacaranda mimosifolia is naturalisedin parts of Kenya and Uganda (A.B.R. Witt pers. obs.) and Tanzania (Henderson 2002).
Jacaranda mimosifolia can grow in bushland, grassland, wooded ravines and riverbanks. The spreading growth habitand the dense foliage shade out native plants and prevent their regeneration.
Deciduous or evergreen tree, 5-15 m tall. Its main distinguishing feature is its spectacular lavender blue blooms which has led to its popularity as an ornamental tree. Jacaranda mimosifoliais fast growing and resprouts easily if damaged. Its bark is thin and grey-brown in colour, smooth when the treeis young though it eventually becomes finely scaly. The twigs are slender and slightly zigzag; they are a light reddish-brown in colour. Twice-pinnately compound leaves, up to 45 cm long. Its flowers are beautiful, lavender blue, tubular, 2.5 cm long, appear in dense 15 - 25 cm terminal clusters with often the entire tree in flower and later the ground turning blue as the flowers fall off. Round, flat, reddish brown, woody capsule, 4 - 5 cm in diameter containing numerous small winged seeds.
Its main value is as an ornamental treewidely grown in urban areas worldwide. It also has medicinal properties. However, these uses cannot compensate for this plant's overall negative impacts.
Jacaranda mimosifolia is regarded as an invasive species in parts of South Africa and Queensland, Australia, where it can out-compete native species. It can form thickets of seedlings beneath planted trees from which the speciesmay expand and exclude other vegetation. J. mimosifoliahas been listed as a Category 3 invader in South Africa (no further planting is allowed - except with special permission - nor is trade in propagative material. Existing plants must be prevented from spreading).
The precise management measures adopted for any plant invasion will depend upon factors such as the terrain, the cost and availability of labour, the severity of the infestation and the presence of other invasive species. Some components of an integrated management approach are introduced below. The best form of invasive species management is prevention. If prevention is no longer possible, it is best to treat the weed infestations when they are small to prevent them from establishing (early detection and rapid response). Controlling the weedbefore it seeds will reduce future problems. Control is generally best applied to the least infested areas before dense infestations are tackled. Consistent follow-up work is required for sustainable management. Jacaranda mimosifolia is very difficult to control once established. Large treesmust be ring-barked or cut down below ground level and any regrowth treated with herbicide. . When using any herbicide always read the label first and follow...

Jacaranda Notes Uses: This fast growing ornamental tree species has been widely planted as a shade and street tree in Adelaide however it is better planted in wider streetscapes, parks and reserves away from over-head power lines and walkways.
