I saw this little entrance garden to a Leisure centre last weekend and thought that the layers of different foliage were really well done. A little bit formal with the three tiered hedges of Acacia cognata dwarf, Austromyrtus inopholia and Westringia in the front.

They had all been clipped quite heavily and were looking the better for it, keeping the differing heights visible and making sure the plants are thick and lush.
There was also some Baekea virgata dwarf (which is fast becoming a favourite plant of mine, even though it grows VERY slowly), to the right and a grafted Eucalyptus ficifolia planted that will come out as a feature tree.
