This bushy evergreen shrub from Australia will overwhelm your senses with its incredibly unique and complex minty aroma and beautiful pinkish purple flowers. Use Australian Mint Bush in teas, try it out in recipes, or just stick your face in the bush to fully immerse yourself in its incredible scent. It is a relative of common culinary herbs such as thyme, oregano, mint and sage. Australian Mint Bush will grow quickly and make a carpet of its purple flowers when they drop in the summer. In areas where severe frost does not threaten you can plant it in ground and use it as an indicator plant for when to water your garden. Prune back after flowering to maintain its bushy form.
