Edible Qualities

Water Mint is a perennial herb that is typically grown for its edible qualities, although it does have ornamental merits as well. The fragrant pointy light green leaves are usually harvested from late spring to late summer. The leaves have a minty taste.

The leaves are most often used in the following ways:

  • Cooking
  • Seasoning

Features & Attributes

Water Mint features bold clusters of shell pink tubular flowers with violet overtones along the stems in mid summer. Its attractive fragrant pointy leaves remain light green in color throughout the season.

This is an herbaceous perennial herb with a spreading, ground-hugging habit of growth. Its medium texture blends into the garden, but can always be balanced by a couple of finer or coarser plants for an effective composition. This is a high maintenance plant that will require regular care and upkeep, and should be cut back in late fall in preparation for winter. It is a good choice for attracting bees and butterflies to your yard. Gardeners should be aware of the following characteristic(s) that may warrant special consideration;

  • Invasive

Aside from its primary use as an edible, Water Mint is sutiable for the following landscape applications;

  • Mass Planting
  • General Garden Use
  • Herb Gardens
  • Container Planting

Planting & Growing

Water Mint will grow to be about 3 feet tall at maturity, with a spread of 3 feet. Its foliage tends to remain dense right to the ground, not requiring facer plants in front. It grows at a fast rate, and under ideal conditions can be expected to live for approximately 10 years.

This plant is quite ornamental as well as edible, and is as much at home in a landscape or flower garden as it is in a designated edibles garden. It does best in full sun to partial shade. It prefers to grow in moist to wet soil, and will even tolerate some standing water. It is not particular as to soil type or pH. It is somewhat tolerant of urban pollution. This species is not originally from North America. It can be propagated by division.

Water Mint is a good choice for the edible garden, but it is also well-suited for use in outdoor pots and containers. Because of its spreading habit of growth, it is ideally suited for use as a 'spiller' in the 'spiller-thriller-filler' container combination; plant it near the edges where it can spill gracefully over the pot. Note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden.
