Verbena, Lemon aloysia tryphylla
Lemon Verbena is known for having the most pure and intense citrus scent and flavor of all herbs. It has no bitterness, so it is particularly well suited for desserts, teas and liqueurs. It also lends itself well to various savory dishes, especially fish or chicken.
Lemon Verbena is deciduous – meaning if grown in a container and brought indoors for the winter, it will loose its leaves in the fall. If it looses its leaves any other time of the year, however, it may be suffering from lack of water or root shock. This plant has a tendency to be leggy, by cutting back regularly you can train Lemon Verbena into nice topiary forms.
Where seasons are short the plants may not produce flowers, but if they do you can harvest them for use. To harvest, strip leaves and chop. One way to preserve the leaves is to add the finely chopped leaves to water and freeze in ice cube trays. Or to dry, hang in bunches in a cool, airy location. Once dry store in an air-tight container.
