Lemongrass verbena (Aloysia triphylla or Aloysia citriodora or Lippia citriodora) is a perennial shrub with an elegant, light and graceful habit that will not withstand the cold except in regions with a mild climate since -4° C makes its stems disappear and -8° C annihilates its stump. This is understandable since lemongrass verbena comes from tropical regions of South America. It should not be confused with officinal verbena (Verbena officinalis) or with lemongrass (Cymbopogon citratus)!
Lemongrass verbena can be recognized by its long, very branched, woody stems with narrow elongated leaves, grouped around the stalk three times, a little rough to the touch, giving off a strong citrus odor when crumpled. She makes small white flowers in summer, which are bluish inside.
It is the leaves of lemon verbena that are sold under the name "verbena" in the radius of herbal teas and not those of verbena officinale. The leaves contain an aromatic essence rich in citral, cineol, limonene and geraniol.
Lemongrass verbena, also known as verbena perfume, has therapeutic properties digestive and sedative, especially in case of mild sleep disorders. On dry and sensitive skin, it has tonic effects.
In addition to herbal teas, lemongrass verbena is used to make a green liquor that is claimed to be digestive! It also perfumes exotic dishes as well as fruit salads and creams.

Advice of care and culture of lemongrass verbena
Its culture is very easy, since the plant is protected from the gel: foot mulching and wintering veil. When the cold has passed and the spring is looming, remove the protections and cut the dry stems. Fold down to 40-50 cm so that the frame rebuilds. Put a little compost underfoot and straw.
During the summer, water regularly. Pinch the ends of the stems so that the verbena is bushy rather than blooming.
Harvest, conservation and use of lemongrass verbena
The leaves to be dried for preservation are harvested twice: in June, when the leaves are ash green and have a light fragrance, then in September when the leaves are dark green and emit a stronger odor. But you can harvest leaves as you need them to use them fresh in herbal tea or in the kitchen.
