The list below contains a small number of local native plants that may be propagated from local cuttings or seed and, having been tried in local gardens, are now growing well in the Canberra region gardens. They are a selection from a much larger group that could be successful and provide both beauty for the gardener and habitat for local critters.

Gardening is meant to be relaxing and fun and the fun thing about these plants is to try and find the right place in the garden for you and the plant. We have found that most of these will grow with an initial watering regime to allow them to establish under almost any conditions. Being local they are used to the vagaries of local soils and climate and some of us have found that they will grow in even the most degraded post-construction situation on a suburban block. After all, buried concrete has been found on a suburban block long after the house has been built.

We have tried to select a small number of local native plants which are fairly representative of vegetation structure, trees, shrubs, grasses and what we have called understorey plants, as well as the floral diversity that many people require to make the effort worthwhile. Understorey in this instance simply means those small but showy plants, such as daisies, that are often overlooked, but play a role in making a garden look interesting, filling in the gaps between the shrubs, trees and grasses. This is what they do in the wild and this is their appropriate role in the suburban garden.

In some cases plants that are usually quite small in the wild will grow to a decent size in a garden, given enough space. This is something you have to think about with local native plants if you want a certain effect. Small native plants, particularly grasses and understorey plants, need space to show their true worth. Believe it or not, what appear to be inoffensive local native shrubs which are not that threatening in their early lives can actually shade out anything after they get going.

All of these have a role to act out in the play that you write. You can vary the mix depending on the effect you want. Alternatively, the shrubs can fill the almost traditional role of a screen while the grasses and understorey plants utilise the middle ground. This is going to be affected by the amount of space you have, perhaps the most important issue in this age of varying block sizes. It’s over to you. Ask the local growers about possibilities.

Happy gardening.
