Corsican Mint

Mentha requienii

Zones 8–13

Growing

This tiny, creeping herb is a standout choice for shady garden corners or as a fragrant living border between stepping stones. Because it forms such a dense, low-growing mat, it can actually withstand being trodden upon, making it an ideal groundcover for walkways. When planting, aim for a slightly acidic soil with a pH between 6.0 and 7.0. While the plant thrives in the shade and prefers to stay evenly moist, you must be careful not to let the soil become waterlogged; excessive moisture can quickly lead to leaf rot.

To keep your mint healthy, allow the surface of the soil to dry out slightly between waterings, ensuring you strike a balance between avoiding drought and preventing rot. If you are propagating new patches, you can easily expand your garden by using cuttings or division. If you harvest the leaves for use, you can store them in the fridge or dry them to preserve that potent peppermint aroma. This miniature perennial is also a wonderful way to naturally deter rodents from garden paths, as the strong scent is known to be unpleasant to rats and mice.
