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.
This vine from Asia first established in the wild in New Zealand as early as 1926.
Like a giant version of the much loved busy Lizzies, shrub balsam can reach up to 2m in height.
