Hi Judith and welcome to Goy, sadly for you we are effectively a western hemisphere group. Hopefully someone who lives in OZ will see your question and be able to help you.

More details needed. What size area? Is it full sun, or part shaded? General description of climate. How dry/hot in summer? How cool are winter months? Is rainfall scarce in your area. What is the soil like, eg is it sandy etc?

Your from Austrailia. That is in the southern hemisphere. I am in the northern hemisphere so I could stand on my head and give you an answer:) but I have a better idea. At the bottom of the GOY web page you will see a row of alphabet tabs, a, b, c...etc. this is the GOYpedia section. Press on (S) and you will see a list of subjects under that category, press on " small garden ideas" or you can press (L) and you will find "low maintenance gardens" press on that subject and might find the subject matter(photos, comments and blogs) that comes up under these two categories helpfull to you as well as others that you might find on your search in addition to those answers given directly to you by GOY members. Right now you should be enjoying nice warm weather, while up here I am shivering in my boots! All the best to you..... Oh yes, one other thing, although this web site originated in the UK, it is in no way balkanized. There are GOY members from all over the world who can help you.

Australia's a big place, with wide climate and conditions, ranging from tropical towards the north, temperate in the south east and south west corners, desert and arid for the bulk of it, so it depends where you are, first, to determine general conditions. Then there's the specific conditions to where you actually are on a much smaller scale, so the extremes of temperature you're likely to experience, and rainfall. Then, on an even smaller scale, what you experience in on your own planting area - full sun, no sun, semi sun, deep shade, rain blocked by trees, or open and windy, near the sea or not, and so on. That information is critical when deciding what plants might grow...

You say different?
I'd look around your area and see what does well, maybe then we would be more help......

As others have said, it would help if we knew which area of Oz. But try Googling "Psoralea pinnata" - you should be able to grow that as you're in a lovely warm country.
