Popped over to Wikipedia and found the following information.
"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.).
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. Other towns and cities in South Africa have Jacaranda trees, but none produce such a show as that of Pretoria.
The city of Brisbane, Australia has a local reputation of having a significant population of Jacaranda trees. The University of Queensland in the city's inner west has a very high concentration of the tree, and due to the impressive display of purple flowers in mid-Spring, which wind up littering vast sections of the suburbs, local folklore claims that "one won't start studying for exams until the jacarandas have molted". At Sydney University there exists a similar expression "by the time the jacaranda in the main quadrangle flowers, it's too late to start studying for exams".
This has led to the slang name "exam tree" or "purple panic" being attached to the plant. At the University of Queensland students even maintain a joke superstition that if a Jacaranda bloom falls on their head during exam time, they will fail an exam. The bad luck can be broken by catching another bloom before it hits the ground.
The reason for the Jacaranda's proliferation in Brisbane is often attributed to the thirties and forties, when new mothers leaving the maternity hospital were given a jacaranda sapling to plant.
Jacarandas in bloom have become closely associated with Brisbane and South East Queensland. The Brisbane City Council have used jacarandas to line avenues, and commercial developments in some areas, particularly along the Brisbane 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 Goodna, and in private gardens. Brisbane's hilly geography allows views of the city and suburbs in which the brightly coloured flowers can be easily seen for miles. The jacaranda has become so much a part of the city's identity that contemporary art, particularly of streetscapes, often incorporates the flowering jacaranda, despite the fact that it only flowers for approximately six weeks from September through October.
The city of Grafton on the north coast of New South Wales, Australia, is also famous for its Jacarandas. Every October the city has a Jacaranda festival during the period of full bloom. A street parade, local public holiday and a series of events are held. A local public holiday sees the city's businesses perform street theatre for passers by and street stalls proliferate. A Jacaranda Queen and Jacaranda Princess are named at a formal ball.
The tree canopies in some of Sydney's north shore and harbour suburbs in the east have a dominant purple glow during late spring."
Well, Mama's not planning to take me to Grafton for the Jacaranda Festival. However, we were able to take some photographs in the grounds of Sydney University last weekend as Mama was there attending a business course. Enjoy the view.
A majestic and glorious specimen standing tall in front of the Student Union's Building.
Purple blooms against blue sky....what a sight.
Fallen blossoms were all over the pavements too.
Look at the centre - those are the much "feared" Jacaranda at the main quadrangle.
I feel like frolicking among those fallen blossoms...come join me.
