Acacia tree species such as A. cognata, A. implexa and others are becoming more popular with landscapers due to the drought tolerant nature of acacias and the improved species now available.
Commonly called ‘Wattle Trees’ are widespread with over 1500 species, nearly 1000 of which are found in Australia. The’ Golden Wattle’ or Acacia pycnatha (pictured below) is the National Floral Emblem of Australia, and being a smaller growing species can be at home in the garden.
Low growing species such as Acacia cognata can look great in a tub and are extremely popular with landscapers, A. cognata is a great plant in rockeries, but works its magic as a low border plant or a replacement for buxus. Look for A. cognata ‘River Cascade’, A. cognata ‘Limelight’ and A. cognata Dwarf ‘Mini Cog’
Acacias are best know for the golden yellow flowers during winter and spring. The ‘Silver Wattle’ or A. dealbata is widely used in urban gardens. A. longifolia or ‘Sydney golden wattle’ is another popular species.
Pictured right is A.beckleri from the Flinders ranges, this acacia forms a rounded bush to 2m, well suited to smalller gardens.
Wattles are easy to grow and generally are regarded as drought tolerant, they handle full sun to light shade and do best when planted as young trees of tubestock. Wattles can be pruned back after flowering to keep a more compact growth habit. A. drummondi is a small growing species, 2-3m.
A. podalyrifolia or ‘Mount Morgan Wattle’ is popular in the home garden. A. baileyana (picture right) is well known as the ‘Cootamundra Wattle’ .
