Acacia cardiophylla is widely known as the Wyalong Wattle and is said to grow to a height of four metres. The specimens, in our garden, reach a height of two metres with a similar spread.
The bipinnate foliage is soft and greyish-green. Golden yellow flowers are carried in globular heads with 20-30 blooms in each head. The heads may be in axillary or terminal clusters. Flowering occurs in spring when blooms are both conspicuous and profuse.
The attractive foliage complements the flowers. Prune after flowering to prevent plants becoming untidy.
Acacia cardiophylla has both attractive foliage and flowers. Wyalong Wattle would be an eye-catching addition to hedges and screens. Also three plants grown close together would create an interesting "stand alone" specimen thicket in a lawn.
Acacia cardiophylla is found on the western slopes of NSW from near Dubbo to the West Wyalong area. We find that the Wyalong Wattle survives and thrives on our well-drained hill. Frosts are not a problem and once established the species has low water requirements.
The species name means heart-shaped and refers to the shape of the leaflets.
Propagate from seed that should be soaked in hot water before sowing.
The type specimen [the original. ed] was collected in the interior of NSW, north of the Macquarie River by Alan Cunningham in the 1840's.
There is also a prostrate cultivar known as Acacia cardiophylla "Gold Lace".
