About

Acacia pendula, commonly known as the weeping myall, true myall, myall, silver-leaf boree, boree, and nilyah, is a species of wattle, which is native to Australia. The 1889 book The Useful Native Plants of Australia records that common names included "Weeping Myall", "True Myall", and Indigenous people of western areas of New South Wales and Queensland referred to the plant as "Boree" and "Balaar".

How to grow it

In The Useful Native Plants of Australia it was noted that "Stock are very fond of the leaves of this tree, especially in seasons of drought, and for this reason, and because they eat down the seedlings, it has almost become exterminated in parts of the colonies."

The tree is available commercially as seedlings or in seed form and has many desirable properties in areas of low rainfall since it is drought tolerant. It is also frost tolerant and will grow in heavy clay soils. It is useful as a shelter-tree or as a windbreak and attracts native birds, particularly parrots who use the seeds as a food source. The rhizobium nodules in the roots also assist in fixing nitrogen into the soil. The blue-grey foliage and weeping habit make it popular both domestically and in overseas cultivation, including in Iran and Kuwait.

Where it grows

It occurs naturally in dry outback areas in Queensland, New South Wales, and Victoria. In New South Wales the tree has a disjunct but widespread distribution throughout inland areas, usually to the west of the upper Hunter Valley. It is often situated on major river floodplains growing as part of woodlands, sometimes as the dominant species, where it grows well in heavy clay soils. In all states it is found to the west of the Great Dividing Range growing in alluvial soils consisting of sand, gravel, silt and clay in areas that receive 400 to 600 mm (16 to 24 in) of annual rainfall.
