Growing Spearmint

Growing conditions: Mint can be started by seed indoors and transplanted to a sunny to partially sunny location outdoors after the danger of frost is past. Shade tolerant. Frequent cuttings spur growth.

Light: sun, partial shade

Height: 18 inches

Spacing: 18 inches

Planting comments: Rhizomes are invasive. If cutting tops is not enough to keep mint from spreading too far, plant a bucket with holes in the bottom in the place where the mint is to be planted. Plant spearmint in the bucket to retain the roots in a small area and reduce its invasive tendencies.

Chef’s Article: Spearmint Flavors More Than Sweets

by Naomi Gallagher

Spearmint is a herb that comes from a perennial plant, Mentha spicata, a member of the mint family, Lamiaceae. Native to Europe and western Asia, it’s now naturalized in many places around the world, especially in moist, damp or wetland habitats. The leaves of spearmint and spearmint oil are used to flavor sweets and beverages.

Spearmint grows aggressively via underground rhizomes and surface runners. Unless the roots are restrained to a small area of a garden by some subterranean means, spearmint will invade areas adjacent to where the original plant was placed. Spearmint grows to two feet tall at which point the stems tend to lay over, as if reaching to grow out further from the mother plant. This helps the plant seek new areas as rooting will occur at the leaf nodes that touch the ground. It’s common to plant mint in pots or planters to contain its growth.

Stems of spearmint are square in cross-section, which is a characteristic shared by most members of the mint family. The bright green toothed leaves lie opposite one another. The leaves appear ruffled and come to a point at the tip, thus the name ‘spear’ mint.

Leaves of spearmint can be harvested throughout the growing season, but the aroma is strongest before flowering occurs. Pruning mint or pinching back the leaves will make the plant bushier and postpone flowering. The leaves can be used fresh, frozen, dried or preserved in sugar syrup or alcohol.

Spearmint is not very commonly used in cooking. Its flavor is more appreciated in beverages, sweets and confections. However, it can be used sparingly with chicken or pork, especially when blended with other herbs and spices. The main aromatic compound in spearmint is menthol. It leaves a cooling sensation in the mouth, so it balances well with spicy hot foods.

Mint sauce and mint jelly are ways to appreciate the cooling peppery taste of mint with other foods. Mint sauce is simple to make. Boil leaves in a heavy sugar syrup until the mint flavor is in the sauce. Then, strain the liquid to remove the leaves and discard them.

Beverages that are flavored with spearmint include iced sweet tea, hot or cold herbal teas, hot cocoa, coffee, and mixed drinks like the mint julep and mojito. Schnapps are liqueurs flavored with spearmint. All these beverages are a little extra special with a garnish of mint leaves.

Spearmint is a flavoring agent in toothpastes and mouth rinses. It’s also a scenting agent in toiletries like soaps and shampoos. Spearmint has antibacterial, antiseptic and antioxidant properties due to its menthol content.
