Jacaranda

http://en.wikipedia.org/wiki/Jacaranda

Jacaranda is a genus of 49 species of flowering plants in the family Bignoniaceae, native to tropical and subtropical regions of Central America, South America, Cuba, Hispaniola and the Bahamas.[1] It has been planted widely in Asia, especially in Nepal. It has been introduced to most tropical and subtropical regions. The genus name is also used as the common name.

Cultivation and uses
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.[7]
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.
Pretoria in South Africa is popularly known as The Jacaranda City due to the enormous number of Jacaranda trees planted as street trees and in parks and gardens. In flowering time the city appears blue/purple in colour when seen from the nearby hills because of all the Jacaranda trees. The time of year the Jacarandas bloom in Pretoria coincides with the year-end exams at the University of Pretoria and legend has it that if a flower from the Jacaranda tree drops on your head, you will pass all your exams.[citation needed]
Jacarandas in bloom have become closely associated with Ipswich and South East Queensland. The Ipswich City Council have used jacarandas to line avenues, and commercial developments in some areas, particularly along the Bremer River have incorporated jacarandas into their landscape design. The trees are common in parks throughout the city, most notably in a long curved avenue in New Farm Park in Brisbane, in Goodna, and in private gardens.

Plant ID: Jacaranda (Jacaranda mimosifolia)  



2014/01/11 に公開
Genus: Jacaranda
Species: mimosifolia
Family: BIGNONIACEAE
Common name: Jacaranda
Plant type: Deciduous
Origin: Brazil


Habit/Form:

A popular, graceful, beautifully hyacinth-blue coloured flower early blooming tree. This tree does very well in the Sydney climate: holding its leaves through winter, dropping leaves in mid-spring, producing new foliage in early summer. This kind of growth habit can also be described as semi-deciduous although it is deciduous in its natural environment.

The size of the species can actually range from 2m shrubs to 30m trees. Usually single trunked, medium tree 12-15m x 12-15m, with a broad dome of curving branches and twiggy canopy. It is not uncommon to find established large size specimens. The trunk has rough, small fissured, mild neat/clean to fairly deep furrow, pale-grey/light brown-tan grey bark.

Jacaranda notoriously hates being pruned. Prunes and wounding usually causes massive epicormic shoots to grow upright, developing unsightly suckers.

This is a vigorous tree that can handle neglect once established, but do not mistake it as having the versatility of a London Plane tree or Brush Box; prefers well drained moist soils, but hardy to most moderately draining soils. Jacarandas tend to be frost tender when young and also like a little wind protection. Can be long lived.


Leaves:

300-400mm long branchlet of opposite bipinnate arranged small leaflets. Each leaflet is lanceolate/elliptic 10-15mm x 3-4mm, bright green, turning yellow in late winter/early spring before falling in mid-spring. New leaves develop in early summer.


Flowers:

40-50mm long campanulate hyacinth-blue (purple-blue) flower, with 5 lobes at the mouth, in large conspicuous 200mm long panicles, faintly perfumed, flowering mid-spring to early summer.


Fruit:

A brown disc-shaped, oblong-oval, follicle/flattened capsule, 50-60mm wide, containing numerous slender seeds.
