Thank you for this list! We are slowly planting mainly native trees around our yard in Meringandan. We must have really severe frosts here as my Scrub Tuckeroo's and Scrub Wilga's were decimated this winter by frost - we didn't get them covered in time (they were put in last October). I'll be sure to try some different trees from this list. I also have some Gumby Gumby's and they have been wonderful - maybe I need to plant more of those :) Rebekah

Thank you for your comments, Rebekah.
It is really difficult to give reliable advice on what grows where. Frosts are so very variable, so it's good to hear what really worked for you.
It is interesting to hear that your gumby gumby are doing so well. I'll move them up to the "heavy frost" list on the strength of your experience. Perhaps you need to put in more of them, as part of the process of planting the trees you enjoy at the same time as creating cover which will let those others grow. You will be surprised, in ten years' time, at the things you can grow which once would have seemed impossible for you.
Cheers,
Trish

Hi Trish, Rhaponticum australe are really frost hardy, Cambooya frost hardy!! - even at the 2 leaf stage...I planted out the babies before Winter and they all survived.
I found the younger Pittosporum angustifolium (those only about 20cm high and experiencing their first Winter) lost all their leaves but they came back as soon as Spring arrived. They had no frost protection. Though the larger saplings don't miss a beat all Winter.

Hi Ros.
Thanks for that. It's good to know.
I am depending on my phone for internet at the moment, but will update the list when I have access to a more sensible computer again.
