This is a most beautiful Wattle and I can see why someone planted it at Wittunga. It flowers from July to October and the flowers were not quite fully open when we were there.
A Western Australian species, it grows 2-4m high by 1.5-2m wide. It needs well drained soil and partial to full sun. This Acacia prefers shelter from strong winds and is suitable for sheltered coastal planting. Light pruning is recommended.
Acacias are beginning to flower and they are earlier around Adelaide and the Hills than here. This is partly the milder climate as well as a little more rain than has fallen here this winter.
Acacia baileyana is a lovely tree in flower. Unfortunately it has become an escapee plant into the wetter hills areas around Adelaide. That certainly does not happen here with this plant.
This is a really useful tree giving a wonderful floral display. It is a hardy and adaptable plant which makes a good windbreak or shelter tree. Pruning extends the life of the tree.
