Maiden’s Wattle

Acacia maidenii has been little planted in the Victorian streetscape, although it should meet most of the requirements for a large street tree. It has an extremely wide native range, growing in coastal Queensland through NSW to north-eastern Victoria (as isolated populations near Orbost). Seemingly, A. maidenii will grow on most soils, as long as they are not fully waterlogged for extended periods.

There are few Maiden’s Wattles in Victorian public landscapes, but an excellent specimen can be seen at Burnley Gardens, where the tree stands about 13m tall, with a broad-spreading canopy. It is growing in turf, and does not have any suckers growing into the grass. It flowers in late summer (January in wet summers) and will normally have a second flowering in late April. This tree was planted at the beginning of this century and shows little senescence.

For best growth, A. maidenii should be planted in any well-drained, organic site. With appropriate summer irrigation, it should grow up to 1000mm per year, forming a broad-canopied tree. Unlike many other wattles, it will grow well in some shade, but will also tolerate full sun.

The phyllodes on Maiden’s Wattle are extremely dark green and long, giving a very lush appearance. It can seed heavily in some locations, and may produce suckers if the roots of mature trees are disturbed. Because we have little experience with this tree in urban horticulture, we cannot recommend planting near bushland sites, unless it is indigenous to that site.
