Prostanthera rotundifolia is naturally found in Australia from New South Wales to Victoria and Tasmania growing on the coast and in the adjoining mountains and extending to inland regions. 

It prefers a well drained fertile moist sandy to light clay loam that is rich and organic in a semi shade to open sunny position and is drought and frost resistant. 

The Mint Bush is grown for its bushy habit and flowers. It is quick growing but short-lived and is planted in new gardens along borders or in rockeries. It is also planted in patio pots or tubs and is suitable for coastal or inland regions establishing in 1-2 years and the grafted forms tend to live longer. ID 176
