Lemon verbena (Aloysia triphylla) is primarily grown as an ornamental plant. There are 37 species in the Aloysia genus related to lemon verbena. In Victorian times, lemon verbena was simply known as the "lemon plant." It was imported to Europe from North and South America, and can be found growing wild along the side of the road in some parts of South America.
Grow Aloysia in full or part sun.
Water regularly to prevent wilt. Soil should be light and well-drained.
Prune the plant in spring. Cut back the main stems to 12 inches and get rid of old wood. This will promote new leaf growth once temperatures rise and the plant is ready to grow again.
Pick fresh leaves for potpourri, herbal teas and flavoring for salads. Leaves are known for their calming, anti-anxiety effects. They are also a mild sedative, relieving problems of the digestive system and reducing fever. Leaves may also be dried for later use.
Propagate plants by softwood cuttings in summer or by heel cuttings in spring once the temperature has reached a minimum 65 degrees Fahrenheit.
