Aloysia citriodora
herbLemon verbena is a tender deciduous shrub grown for narrow, glossy leaves that carry the purest, most intense lemon fragrance of any herb. Native to South America, it reaches 3 to 6 ft in warm zones 8 to 11 and is easily kept in a pot and overwintered indoors in colder climates. It is prized for teas, desserts, and potpourri.

Lemon verbena is almost always started from a nursery plant or cutting rather than seed. Plant it out after all danger of frost in full sun and light, fertile, well-drained soil. It loves heat and resents wet feet, so water when the surface dries and never let it sit soggy. Pinch and harvest often to keep it bushy. In zones below 8, grow it in a container and bring it indoors before frost; it may drop its leaves and rest over winter, which is normal.

Most common on stressed or indoor plants; raise humidity and rinse the foliage, especially the undersides
Watch overwintered indoor plants, use yellow sticky traps, and isolate new plants
Hose off colonies on tender tips and encourage ladybugs outdoors
Snip young shoots and leaves as needed once the plant is about 10 inches tall; the youngest growth has the strongest lemon fragrance. Harvest in the morning and cut sprigs regularly to keep the shrub bushy. The leaves dry and store exceptionally well, holding their scent for months.
Intensely lemon-scented leaves are rich in aromatic essential oils and are used fresh or dried for herbal teas, desserts, syrups, and to flavor fish and poultry. The fragrant summer flowers also draw bees and other pollinators.
