To Buy: 
Buy dried lemon myrtle leaves whole or ground from a reputable retailer.  To get fresh leaves it would probably be necessary to purchase a tree from a native nursery and put it in your garden.
To Store: 
Store whole and ground leaves in airtight containers away from light and heat.  Whole leaves will last for up to three years, ground for at least 18 months.
Tips & Tricks: 
Use in stir-fries and Asian curries as a lemongrass substitute.  Add towards the end of cooking, no more than 10 minutes before serving, as long cooking destroys the delicate lemon notes.  Use sparingly, or a camphor-like eucalyptus taste will override the lemon.
