Edible Parts: Leaves.
Edible Uses: Condiment, tea.
Leaves - occasionally cooked as a spinach but more commonly used as a flavouring in salads, fruit salads etc. A delicious lemon-like flavour, it is adored by most people who try it. A delicious and refreshing tea is made from the leaves. The dried leaves will retain their lemon aroma for many years.
An undervalued medicinal herb, lemon verbena contains a strong
lemon-scented essential oil that has calming and digestive qualities.
The plant has a gentle sedative action and a reputation for soothing
abdominal discomfort. It has a mildly tonic effect upon the nervous
system and helps to lift the spirits and counter depression. The
leaves and the flowering tops are antispasmodic, febrifuge, sedative
and stomachic. A tea made from the leaves has a deliciously refreshing
lemon flavour and is used mainly in treating digestive disorders
such as flatulence, indigestion and acidity. Some caution is advisable
though, since prolonged use or large internal doses can cause
gastric irritation. The herb is also useful as a stimulant for
treating lethargy or depression whilst it is also used to treat
feverish colds. The essential oil is used in aromatherapy in the
treatment of nervous and digestive problems and also for acne,
boils and cysts.
Essential, insecticide, reppellent.
An essential oil obtained from the leaves is extensively used in perfumery. An average yield of 0.5% is obtained. There is some evidence that the use of this oil can sensitise the skin to sunlight and so its use has been largely replaced by the tropical plant lemongrass, Cymbopogon spp.. The dried leaves retain their fragrance well and so are used in pot-pourri. The growing plant repels midges, flies and other insects. The essential oil is an effective insecticide in 1 - 2% concentration.
Succeeds in most moderately fertile soils if they are well-drained. Prefers a light soil. Requires a sunny sheltered position. Requires a warm damp climate. A very ornamental plant, lemon verbena is only hardy in the milder areas. It can withstand about 10°c of frost. It generally survives most winters outdoors if growing in a suitable position, though it is often cut back to ground level and then resprouts from the base in late spring or early summer. Giving the roots a good, thick organic mulch will confer extra protection from winter cold. The plant succeeds outdoors at Howick, a garden on the coast of Northumberland. The leaves are very aromatic with a lemon scent, they are often used to make a drink or for their essential oils. There has been considerable confusion over the naming of this species. We are following the treatment used in and , which is also the current treatment in the 1999 edition of The Plant Finder. However, the book 'World Economic Plants' uses the name A. citrodora Palau (a different author to the one we cite) as the correct name. Any pruning is best carried out in the spring. This species is notably resistant to honey fungus.
Seed - we have no information for this species but suggest sowing the seed in a greenhouse in late spring. Only just cover the seed and keep in a light position, making sure the compost does not dry out. When large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for at least their first winter. Plant them out in early summer and give some protection from the cold for at least their first winter outdoors. Cuttings of softwood, May/June in a frame. Grow on for at least their first winter in a greenhouse and plant out in late spring after the last expected frosts. The cuttings root quickly and easily, though there can be losses in the first winter. Cuttings of half-ripe wood, August in a frame. Grow on for at least their first winter in a greenhouse and plant out in late spring after the last expected frosts. The cuttings root quickly and easily, though there can be losses in the first winter.
