The lemon balm plant is 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 is 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.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.
