The maps below show the areas where warm season grasses will hold their colour throughout winter.
Outside these areas, temperatures are colder and warm season grasses go dormant during winter and warm season grasses will need to be over-seeded with a cool season grass such as Ryegrass to give winter colour and protection from wear. In very cold areas and where summers are not that hot, cool season grasses should be considered.
If your location is identified as being suited to a warm season grass, the best warm season variety is Village Green. Originating from the Mediterranean region of Australia, Village Green is well adapted to warm to hot dry summers and cool winters, conditions that match the zones highlighted in the maps.
