Description

Mentha aquatica is a herbaceous perennial plant that grows up to 35 inches (90 cm) tall. The stems are hairy to nearly hairless and green or purple. The rhizomes are wide-spreading, fleshy, with fibrous roots. The green, sometimes purplish leaves are opposite, ovate, toothed, hairy to nearly hairless, up to 2.4 inches (6 cm) long, and up to 1.6 inches (4 cm) wide. Flowers are tubular, densely crowded, pinkish to lilac, and form a terminal hemispherical inflorescence. Flowering is from mid to late summer.

How to Grow and Care

Mint is one of the few culinary herbs that grow well in shady areas, although it can handle full sun if kept watered.

Cuttings of Mint will root easily in soil or water, and mature plants can be divided and transplanted. However, you can start new plants from seed. Sow outdoors in late spring or start seed indoors about 8 to 10 weeks before the last frost. Keep soil moist until the seed germinates.

Mint prefers rich, moist soil with a slightly acidic pH between 6.5 and 7.0. If the soil is somewhat lean, top-dress yearly with organic matter and apply an organic fertilizer mid-season after shearing.

To contain the roots and limit spreading, you can grow Mint in containers above or sunk into the ground. However, be careful to keep container Mints from flopping over and touching the ground. Stems will quickly root if given a chance.
