Corymbia Citrodoria (lemon scented gum) absolutely beautifully scented after rain.
Corymbia ficifolia (flowering gum, nuff said)
I live in coastal melbourne and I absolutely love the Leptospermum (coastal tea tree). Such beautiful flowers in spring. I actually have made one of these into a hedge and another one I have shaped into a living feature overhanging my pool giving me shade when i'm swimming in it.
