Round Leaf Mint Prostanthera rotundifolia is often called Native Basil and Native Oregano, common names can be conflicting with the botanical name, but they do give the user something to relate back to what they know. Native Basil has a Marjorim/basil flavour and is a great addition to your pantry.  Once you get used to using it on any pasta sauce you might make, or even in a bread with perhaps some native pepper, mixed in with a creamy cheese, the uses are endless, just limited by your imagination. Some, like River Mint Mentha australis have  a strong spearmint taste and aroma, whereas the Round-leaf or Bush Mint is more like your traditional mint with a slight aromatic edge.  The early settlers used Australian native mints to make mint sauce for their Sunday roast lamb.  This native bushfood herb is just as versitile as the traditional mints and can be replaced by them, use a little until you get used to the strong minty flavour.
