Acacia boormanii
Family: Fabaceae

Common name:  Snowy River Wattle

Acacia boormanii is a suckering, copse-forming tree that provides ideal growth for many landscapes. This tree is able to grow in restricted sites, in areas where breakable stems are needed, and sites where screening is desired. We have seen A. boormanii used successfully in parking lots in the ACT, in freeway plantings, and as a massed small tree.

In late winter, A. boormanii is covered with fine lemon-yellow flowers borne in panicles. These flowers last for 4-6 weeks, and compliment the fine, grey-green foliage admirably. When not in flower, this foliage provides an excellent, lush mass, and with proper maintenance, can retain its foliage to the ground.

In its native range, Snowy River Wattle is known to tolerate some salinity in its soils. It also seems to tolerate relatively compacted, clay soils well, although it thrives on freely-draining soils high in organic matter. This tree is probably not strongly drought tolerant, and will grow best with some summer irrigation post-establishment.

Its multi-stemmed, mallee growth makes this an easy tree to manage. Experience with trees at Burnley College indicates that pruning back to the base every 5-8 years will give a slightly suckering tree retaining most of its basal foliage. If needed, A. boormanii can have this basal foliage easily removed to give sight lines at eye level.

Overall, A. boormanii is an excellent small tree that will fit into many “difficult” landscape situations, while having fine aesthetic characteristics at the same time.
