My luma is very happy and doing well since getting into the ground. I have a friend who had a nursery and I was given a lot of her leftovers after she closed her business....items that had been in pots for far too long and it's rewarding to see them doing so well once they were 'set free'. It's interesting to grow plants that had been unfamiliar to me and some of the Aussies are still unknown to me, waiting for them to flower in some form to be able to identify them.
We are in a 'city' situation now and starting 'from scratch' on a small lot, not used to lacking privacy...an existing large cotoneaster and a short hedge were the extent of our privacy screen, several old trees having been taken down before we bought the property....so the 3 luma and 1 halleria are now the backbone of our front border, plus 1 Vine Maple, miscellaneous grasses and smaller shrubs.
It sounds to be beautiful where you are...we would love to see pictures if you get the chance....
edited to add...it's interesting that so many of our gardens are truly international...I've also just planted a Bolivian Fuchsia. Perhaps we should have small flags for our gardens, showing the plant's point of origin...lol..
