Tourists have descended on a unique Sydney street to take pictures with a canopy of bright purple flowers.

The Jacaranda flowers, which bloom for six weeks during the Australian summer, are out in force in McDougall Street in the neighbourhood of Kirribilli.

Local residents said they have seen hundreds of tourists flocking to the street to take pictures with trees bearing the flower.

They warn that the floral fans are now causing traffic problems and are calling on North Sydney Council to put proper plans in place for next year.

The chair of a residents’ group, Jillian Christie, told the Sydney Daily Telegraph: ““It’s difficult to drive there without hitting a tourist. They are out in the middle of the road.

“We all love it and we are understanding but we don’t want the tourists hurt.”

She has called for an official jacaranda festival to be organised and for the street to be made one-way for the six weeks the flowers are in bloom or have a small section closed completely to traffic.

A spokesman for the council said they were aware of the increasing popularity of the flowers and the problems they were causing.

She said: “The feasibility and costs of a traffic management plan and a jacaranda festival are being considered for the future”.
