Water Conservation Garden

An attractive display of Australian and exotic plants with low water requirements for use in the home garden.

The Water Conservation Garden is designed to demonstrate water saving techniques. Signs at the garden explain ways to save water, such as plant selection and mulching. The design and planting of the garden give ideas and inspiration to the home gardener. The plants grown come from countries with a climate similar to Melbourne’s and show a range of form and colour. Most of the plants are available in general nurseries, some are found only in specialist nurseries.

Curator Notes

  • Ornamental grasses are a feature of the garden; these are cut to the ground at the end of each winter.
  • Yuccas are handsome plants but are almost impossible to remove and have sharp spines, use with caution.
  • Controlling weeds reduces competition for water.
