This vine from Asia first established in the wild in New Zealand as early as 1926.
A very fast growing, though thankfully short lived tree - popping up on cliffs, banks, hillsides, slips and cuttings. One of the few flowering trees around in winter, brush wattle is conspicuous now with greenish-yellow bottlebrush-like flowers. It is reasonably common in the North Island, though rarer in the south.
Like a giant version of the much loved busy Lizzies, shrub balsam can reach up to 2m in height.
