While not as popular as other herbs, lemon balm is nevertheless a wonderful herb to have in your garden. The lemon balm plant (Melissa officinalis) is actually a member of the mint family and is a perennial herb. It grows as a bushy, leafy herb with a pleasant lemon smell and small white flowers. If not carefully controlled, lemon balm can quickly become invasive in the garden. Often, people mistakenly think that lemon balm is invasive due to its roots, like its cousins peppermint and spearmint, but in fact it’s the seeds of the lemon balm plant that cause this herb to suddenly take over a garden. Removing the flowers of the plant as soon as they appear will make your lemon balm far less invasive.
Growing lemon balm is very easy. The plants aren’t picky about where they grow and will grow in almost any soil, but they prefer rich, well drained soil. Lemon balm plants will grow in part shade to full sun, but flourish best in full sun. Once established, lemon balm can produce large amounts of its sweet, lemon smelling leaves. These leaves can be used for a variety of things. Most commonly, lemon balm leaves are used in teas and potpourris. You can also use lemon balm in cooking, in making essential oils and as an insect repellent.
