Location in Garden

Is planted near the toilets on Lakeside and can also be found in the Fruit Loop and scattered around the Connections Garden.

 

Many of our popular garden plants are grown for their bird attracting qualities, usually for their nectar-producing flowers. But it is also important to provide habitat in the garden for insects and the birds which come to eat them.

As you can see in the photograph, the lemon scented myrtle is very popular with the insects, its creamy-white flowers attracting a wide range of beetles, bees and other insects.

It is called ironwood because of its very hard timber.

Although it is not common in nature, it is popular in cultivation, both in the Queensland tropics and in southern Australia, where it only reaches the size of a tall shrub and can suffer in heavy frosts. The masses of flowers reaching to the ground make it an ideal garden specimen.

All of the Backhousia species, which are found only in Australia, have individual aromatic scents.
