In an avenue leading up to the former home of Dame Elisabeth Murdoch (mother of Rupert), in Victoria, lemon-scented eucalyptus lines the drive. Fondly known as gum trees, 700 species of eucalyptus provide the lofty canopy in Australian landscapes, as iconic as the middle-story tree fern.
Cider Gum Eucalyptus - striking! I want about a dozen of these to line my road to my house!
Acacia cognata ‘Limelight’ from our RHSChelsea best in show
Native Violet, Viola hederaceae - I use it everywhere, with its bright green leaves and its sweet mauve/purple flowers raised above the foliage. It will rapidly fill in bare areas of soil between stepping stones.
