Tipuana Or Rosewood Tree: A Declared Weed
A declared weed in Queensland, the rosewood (Tipuana tipu) is also known as the yellow jacaranda for its yellow flowers that bloom during jacaranda season. It is native to South America, which explains another of its common names, the pride of Bolivia.
Unfortunately, though, this tree is a widespread pest in south-eastern and central Queensland. In the past, people planted it as an ornamental and shade tree. However, it now poses an environmental threat to woodlands, riverbank vegetation communities and urban bushland in sub-tropical regions.
How To Recognise A Tipuana Tree
You can recognise a Tipuana tree easily in spring to summer, when it is in flower. It produces masses of bright yellow to orange-yellow pea-shaped flowers during this season. They then become winged seeds 4 to 7cm in length that rotate as they fall to the ground.
The rosewood tree grows quickly to reach 15m in height, and it is capable of reaching 30m or more. It is deciduous, and has rough bark on its main trunk. The leaves of the rosewood are small and oval-shaped, and arranged alternately along a stalk that is usually 15 to 20 cm long. The tree reproduces only by seed. These are readily dispersed by wind and water.
The Brisbane City Council has a weed identification tool that you can visit to learn more.
What To Do About Removing A Tipuana Tree
If you think you have a Tipuana tree growing on your property, you don’t have to notify the council. The council’s policy is to reduce the number of these pest trees, however, so you should consider having it removed. Don’t compost it.
There are several recommended removal methods for the Tipuana tree. These include basal bark, stem injection, cut stump and foliar spray. We will advise you on our recommendations for the best removal method for your tree. We can also provide suggestions for trees to replace it once removed.
