On the Southern Peninsula we sit on limestone bedrock, formed two million years ago. Over time the ocean and the wind has uniquely shaped the limestone creating this rugged rocky coastline. The best spots to see the limestone cliffs are in the Mornington Peninsula National Park.

Limestone has been made through the ice ages over the last million years. Limestone formed from the shell remains of sea creatures. Acid within rainwater dissolved the shells which then precipitated as calcium forming limestone deposits throughout the sand dunes.

The colours in Limestone vary. From light to dark coloured ochres to soft salmon coloured pinks, to the dominant colours being creams and whites.

Many gardens on the southern peninsula have limestone rocks throughout the garden or under the soil. When planting a local native garden some areas of soil are soft sand while other areas have limestone rock very close to the surface.

Limestone is a beautiful looking rock, ideal for placing around plants in a southern peninsula native plant garden. Limestone rocks provide habitat for two well loved garden friends, skinks and blue tongue lizards. If your very lucky your limestone rock pile could provide a home to a Jacky Lizard (also called Jacky Dragon). Limestone like all rocks warm up and hold heat in the sun. As well as providing shelter, reptiles need these heat holding rocks to stay warm.
