Some Sustainable Plants for a Coastal Temperate Climate
These plants are climate-friendly (that is, sustainable) in a Victorian seaside garden in the temperate climate of Australia’s southern coast. Some are indigenous to that region, some are native to Australia and some come from elsewhere.
Blue fescue (Festuca glauca): These small, blue, tufted grass plants provide a nice contrast in the garden and lizards love to hang around them.
Common correa (Correa reflexa): This lovely little shrub grows wild in the region, with little hanging bell flowers all over it, some red and others a dusty pink.
Common heath (Epacris impressa): The dark green, short pointy leaves and clusters of narrow little bell flowers along the stem, which are sometimes pink, sometimes white, are a Victorian classic.
Geraldton wax (Chamelaucium uncinatum): This magnificent Western Australian shrub, with its masses of pale pink, waxy flowers in spring also suit this region of Victoria.
Grampians thryptomene (Thryptomene calycina): Tiny, tiny aromatic leaves and weeny white flowers packed on the stem in spring make this a favourite in many gardens in the area.
Hebe, particularly the ‘Icing Sugar’ variety: This shrub is tough as old boots and grows all over the place, and the tough green leaves and pink and white flowers make it stand out in any sustainable garden.
Liriope (Liriope muscari): A clumping, strappy plant with shiny green leaves that always deserves a spot in the garden; the flower spikes in blue or white are an added bonus.
New Zealand Christmas tree (Metrosideros excelsa): A New Zealand favourite, this great tough tree, with bright red flowers in summer, is just right for a garden near the sea.
Sage, or salvia: All kinds of salvia in all kinds of colours, some tougher than others, are terrific in just about any sustainable garden — you can find at least one, if not six or seven, for your garden.
Toothed lancewood (Pseudopanax ferox): Another Kiwi plant, this one starts off with long-toothed narrow leaves pointing downward, and then matures into a large, rounded, spectacular tree — often loved for its weirdness.

pH
