An essential oil is obtained from the plant (the exact part is not specified, it is probably the entire plant and especially the flowering stems). It is used medicinally. The whole plant is very pleasantly aromatic, the aroma lasting for a long time after the plant has been harvested. It is therefore a very useful ingredient in pot-pourri.

How it is grown
A very easily grown plant, it succeeds in any well-drained soil in a sunny sheltered position. It prefers a light rich moist soil, a warm position and partial shade. Once established, this is a drought tolerant species, it is a useful plant to try in difficult dry places, usually succeeding in the dustiest of soils once it is established. Lemon balm is often grown in the herb garden, and sometimes also commercially, there are some named varieties. Plants can often self-sow so freely as to become a menace. If the plants are cut back hard after flowering, they will produce a fresh flush of leaves. Members of this genus are rarely if ever troubled by browsing deer or rabbits. A good bee plant. A good companion plant, especially for brassicas. Special Features:Attractive foliage, Edible, Fragrant foliage, Not North American native, Invasive, Naturalizing, Suitable for cut flowers, Suitable for dried flowers. The plant is heat tolerant in zones 12 through 1. (Plant Hardiness Zones show how well plants withstand cold winter temperatures. Plant Heat Zones show when plants would start suffering from the heat. The Plant Heat Zone map is based on the number of "heat days" experienced in a given area where the temperature climbs to over 86 degrees F (30°C). At this temperature, many plants begin to suffer physiological damage. Heat Zones range from 1 (no heat days) to 12 (210 or more heat days). For example Heat Zone. 11-1 indicates that the plant is heat tolerant in zones 11 through 1.) For polyculture design as well as the above-ground architecture (form - tree, shrub etc. and size shown above) information on the habit and root pattern is also useful and given here if available. The plant growth habit is a clumper with limited spread. The root pattern is fibrous dividing into a large number of fine roots. The root pattern is stoloniferous rooting from creeping stems above the ground.
Propagating it: Seed - sow spring or autumn in a cold frame. Germination can be slow. Prick out the seedlings into individual pots as soon as they are large enough to handle and plant out into their permanent positions when the plants are at least 15cm tall. If there is plenty of seed it can be sown in an outdoor seed bed in April. Plant out into their permanent positions the following spring. Division in spring or autumn. Very easy, larger clumps can be replanted direct into their permanent positions, though it is best to pot up smaller clumps and grow them on in a cold frame until they are rooting well. Plant them out in the spring. Cuttings in July/August.
