This strongly scented herb (Mentha aquatica) smells similar to peppermint and requires high moisture to thrive. Water mint is known for its pretty, sphere-shaped lavender flowers; however, it's the leaves that hold the herb's medicinal and culinary benefits.
Water mint can be dried for use in teas to treat digestive problems, fevers, or headache and is also used as a sore throat and mouth gargle. The herb can also be used fresh in salads and other culinary dishes.
