Spearmint

Mentha spicata

Characteristics

Culture

Best grown in rich, moist soils in full sun to part shade, Spearmint adapts to a wide range of soils except dry ones. Large plantings may be sheared after bloom to remove flower spikes and stimulate new vegetative growth. Spearmint is in the Lamiaceae family, so soil barriers or containers may be used to restrain rhizomatous spread if plants are grown in borders or other areas where spread is unwanted.

Noteworthy Characteristics

Mentha spicata, an upright perennial thrives in full sun in well-drained soils moist growing quickly 1 to 2 feet high and wide with bright green leaves and shoots; and it spreads by rhizomes to form an attractive ground cover. It features ovate to lanceolate dark green leaves (to 3″ long) and terminal spikes of small lilac to pink to white flowers in summer.  Spearmint can be distinguished from other mints by its almost hairless (glabrous) leaves that are attached to the stem with a very to amost non-existant petiole (sessile).  The square stems can root wherever they touch the ground and it also spreads by rhizomes.

Leaves have a strong spearmint fragrance and taste, and may be used to flavor teas, in salads, or in potpourris. It is widely used for culinary purposes and is known as one of the best mints for flavor. Use the flowers and leaves fresh or dried in teas, beverages, jellies, syrups, candies, ice creams, lamb dishes, and mint sauce.

Problems

 Fungal diseases are common. May find rust and leaf spot. Spreads aggresively.

Garden Uses

Ideal in containers. Herb gardens. Naturalize Spearmint as a ground cover in moist informal areas such as pond/water garden margins or low open woodland areas.
