Japanese mint

Grow in moist but well drained soil in full or partial sun. To prevent it becoming invasive, restrict the root run in a deep container and plunge into the ground, or plant in a well chosen site where it can grow unrestricted. This variety does tend to be less invasive than other mints. See mint cultivation for more information
