Acacia cognata are a narrow leafed wattle, sometimes called the ‘River Wattle’. It is the smaller growing cultivars including ‘Limelight’, ‘Green Mist’ and ‘Waterfall’ that are most popular and all have been developed from the natural form, which is a small weeping tree.
The newer cultivars especially dwarf forms such as Acacia cognata ‘Limelight’, Acacia cognata ‘Lime Magik’ and Acacia cognata dwarf ‘Mini Cog’ are perhaps one of the most successful developments in Australian Native plants in recent years with a number of varied cultivars being developed.
Acacia Cognata plant profile
Becoming particularly popular especially the dwarf or low growing forms such as Acacia cognata ‘Limelight’, Acacia cognata ‘Lime Magik’, Acacia cognata dwarf ‘Mini Cog’ and ‘Little Con’ are all popular.
All A. cognata do well in full sun to part shade and prefer a drained soil. Pruning is not generally required although tips can be trimmed to keep in shape.
An all purpose Australian Native Plant fertilizer applied in spring will benefit growth
Acaia Cognata ‘Bower wattle’ or ‘River Wattle’ cultivars all prefer a sunny well drained position. Once established Acacia Cognata species are relatively drought tolerant and are useful both as specimen plants and as hedging plants.
A. Cognata cultivars vary in height from 75cm through to 6-8m. The dwarf forms receive much attention, however we believe that that the taller growing cultivars such as A. cognata ‘Copper Tips’ are also of equal value in landscaping especially for use as screening plants.
