Spearmint is a perennial with fragrant, lance-shaped leaves. Flowers appear on dense, cylindrical spikes, with tubular, white, pink or lilac blooms. Like other mints, spearmint spreads by stolons and rhizomes, and so should be planted were its spreading habit doesn't matter or in a place where it can be contained. Spearmint leaves are smaller than peppermint leaves, and have a variety of culinary uses, including jellies, candy, and beverages. Very aromatic foliage. Grows 1 to 2 feet tall and spreads until it is stopped.
Mints grow best in rich, moist soils in full sun to part shade, though not overly wet soils. Adapts to a wide range of soils except dry ones. May be sheared after bloom to remove flower spikes and stimulate new vegetative growth. Soil barriers may be used to restrain rhizomatous spread if plants are grown in borders or other areas where spread is unwanted, though, honestly, if spreading is a concern, plant it elsewhere or in a container.
