Here at Australian Plants Online we frequently get asked "what are the best plants for my garden in Central Coast/Far North Queensland/Inner West Sydney/etc" - and we have a standard response.

You know your own garden better than us.

If we suggested plants for Queensland, they would have to thrive in climates ranging from the hot dry dusty outback of Mount Isa to the mild coastal urban hills of Mount Coot-tha to the steamy rain-soaked tropics of Mount Bartle Frere.
The same goes for all the other states - Australia is a continent as well as a country and has multiple climates and soil conditions within the same state.

There are three foolproof ways to find the best plants for your state, and your garden:

1. Look at neighbours' gardens.

What's flourishing there? What's looking under the weather, even in an otherwise-lush garden? What's always in flower, or clothed in healthy foliage?

2. Visit local gardens.

Every state has a botanic garden, public park, or large green space open to everyone, and often free to visit. Wikipedia lists over 140 Australian botanic gardens alone, so you've lots of choice. Go along to your nearest one and see what's planted there - take a notebook so you can record the names.

Watch out for charity open days too, when you can sticky beak in local private gardens for a small entrance fee. The homeowners who garden these plots are often extremely knowledgeable about what they grow, and happy to share that knowledge.

3. Look at your own garden.

Notice where the sunlight falls each day, and for how long. Record maximum and minimum temperatures. Are there any pockets of frost? Does it get battered by wind? What is your soil like - silty, rocky, rich loam or dry dust? Acid or alkaline? Free-draining or boggy in patches?

Your garden will be completely different in its microclimates (and even soil type) than a garden in the next street, so your own records and observations will be the best guide to what you can grow successfully.
