Whorled Mint is the hybrid between the two most common mints in the UK, Water Mint and Corn Mint but smells similar to Corn Mint (i.e. variously sickly, pepperminty, or like caraway). It is similar in habit to Corn Mint but grows higher than 60cm to 90cm and is more robust. The leaves are between 2 to 6.5mm long.
