About This Plant

Scotch Mint is a naturally occurring sterile hybrid of Spearmint (M. spicata) and Field Mint (M. arvensis). It has a very strong and especially sweet Spearmint aroma and flavor. It is cultivated for its essential oil and is one of the main contributors to the American Mint oil industry.  The world center for growing Scotch Mint for commercial use is in the U.S. Pacific Northwest and it is used almost entirely for processing into Mint flavors for chewing gum, candies and rat repellent. The Vietnamese use Scotch Mint in the making of Pho. 

Scotch Mint is an easy-to-grow herbaceous perennial that grows 1 ½ – 2 feet tall and is hardy in USDA zones 5-9.  Its leaves are thinner and more delicate than Spearmint, typically up to 2 ¾” long. The gold and green variegated leaves have beautiful bright yellow stripes and serrated edges. Its light purple flowers form in whorled clusters along the axils.  Its growth is more compact than other Mints. It thrives in distubed, moist ground, especially along the shores of waterways.  It smells like Spearmint and has a bit of a Peppermint-like bite.

Scotch Mint was first introduced to North America by a gardener in Wisconsin in 1908.  From there, it began being cultivated throughout the Midwest and later in the Pacific Northwest. Spearmint (M. spicata) had been introduced to the U.S. in the 1800’s for oil production. After 1908, Scotch Mint became the cultivated variety of choice.

Sowing

Scotch Mint is a sterile hybrid that rarely sets seed; when it does, the seeds are rarely viable.  It is propagated rather by plant cuttings and division.  Division can happen at any time of year but is best done in the Spring or Fall. 

Transplanting

Scotch Mint can be spaced about 12 – 18” apart.

Cultivation

Scotch Mint will grow well in any type of soil, including heavy clay, as long as it’s well-watered.  Growing it in full sun will result in the best flavor and aroma, though it will grow in partial shade as well.
