Aloysia triphylla, the Lemon Verbena (also known as yerba Louisa), is a large tender shrub native to South America mainly, Argentina, Peru, and Chile. It gets its common name from the strong lemony scent and flavor given off by the leaves when they are crushed or brushed against. Lemon Verbena belongs to a group of plants called citrus mimics,which, as can be inferred, all have citrusscented foliage. The lemon verbena plant has more lemony than the actual fruit. The plant blooms during late summer, though the small, white, inconspicuous flowers arent very ornamental.

Though the two plants share the same name, lemon verbena has no resemblance to the verbena flower, which is quite attractive. Thats not to say that lemon verbena isnt attractive, its just not decorative. Lemon Verbena has narrow oval leaves in whorls of 3 or 4. It reaches a height of 610 feet when grown in the garden, less in containers. The tiny lavender or white flowers appear in early summer and bloom for several weeks. They are borne in a loose, pyramidshaped panicle at the ends of the stems.

Lemon Verbena Uses

Lemon verbena plant has the most potent citrus smell out of any herb in existence, fresh or dried. The potent aroma has many uses, one of the most common is to add scent to potpourri. The stems or leaves can be chopped and added directly to the potpourri to add the smell of fresh lemon. In days long past, women used to stuff lemon verbena in their hats, sleeves and clothing to improve their smell, almost as a kind of natural perfume. Back then, the scent was thought to promote intimacy, though this is now known to be untrue.

Whether you grow it in a container or in the garden, plant Lemon Verbena where you can take advantage of its fragrance. Put it near a pathway or place a small pot in a sunny kitchen window. The leaves can be used in potpourri or added to iced drinks. Lemon Verbena makes an excellent herbal tea. Add a sprig or two to a bouquet, or float some in small finger bowls. Lemon Verbena can also be used in cooking, for example, in sauces for fish or chicken. Put a leaf in the bottom of a jar when making jelly. Lemon Verbena is only winterhardy in the mildest climates, but it can be successfully grown outdoors all year in a container if given winter protection.

Growing Lemon Verbena

Planting against a warm southfacing wall will allow it to survive in areas with cooler winters. Otherwise, Lemon Verbena can be grown indoors in a cool position all year or placed outdoors for the summer. It can stand on the patio or the whole pot can be sunk to its rim in the garden. Bring it in again when the weather turns cool in fall.


Lemon Verbena is easy to propagate from tip cuttings taken in spring or early summer. Take cuttings from the pruning done in spring, or use the pinched tips removed later. The cuttings should be 34 inches long. Remove the lowest leaves, dip the cut ends in rooting powder, and insert them in a moist mixture of peat moss and perlite. Cover this with a perforated plastic bag and place in a bright spot away from direct sunlight. Once the cuttings have rooted, they can be repotted into individual pots and otherwise treated as mature plants. Normal indoor temperatures are fine during the growing season. Though the plant is a longlived perennial, it cannot tolerate freezing weather, so must be grown in a container in all zones but 8 through 10.

Plant in a small container and keep in a location that receives full sunlight throughout the day. Water once every five days during spring and summer, and once every week during fall and winter. Feed once per month with a balanced 101010 NPK fertilizer during spring and summer.

Care in Different Seasons

Harvest the plants foliage during summer by cutting the plant back to half its height and saving the removed section. During the winter, Lemon Verbena grows over winter indoors in all but the mildest climates. It thrives best if placed in a bright, but cool position; 50°60 °F is considered optimum during the day. The night temperature can go as low as 40 °F. Water sparingly, keeping the soil on the dry side, and dont feed. During the spring, remove Lemon Verbena from its pot and carefully shake off the old soil. Repot in fresh soil; welldrained commercial potting soil is fine. Older, larger specimens can be topdressed instead. In February to March, the plant can be pruned back by onethird to half its shape. Step up watering and begin feeding every 3 weeks.

During the summer, regular watering is a must and dilute liquid fertilizer can be added about every 2 weeks. In the fall, prepare Lemon Verbena for its winter rest. Outdoor plants should be brought indoor or placed in a sheltered position. Lemon Verbena is one of those rare plants that insects or diseases hardly ever bother. Even aphids seem to leave it alone. The only problems likely to be encountered are in the overwintering. If plants are kept too warm and wet in winter, soft, leggy growth will result. Mites may be a problem in warm dry conditions indoors.

Prevent an attack by keeping plants in a cool spot and misting frequently. Lemon Verbena is usually available at most nurseries and garden centers. The plant is known to live for many years. The leaves as well can be used all year. They bloom more in summer. They have narrow oval leaves in whorls along the stems as they can grow as large as 6-10 feet. The leaves also have fast-growing ability. The flowers are scentless, but the leaves have a strong lemony fragrance when crushed or brushed against. Panicles of tiny white or lavender flowers at the ends of the stems for several weeks in early summer. Lemon Verbena is delightful anywhere its scent can be appreciated; by a doorway, along with a garden path, or on a windowsill in the kitchen.


  • Water regularly springfall.
  • Never let the soil dry out. Reduce watering in fall, and keep it to a bare minimum in winter.
  • Add dilute liquid fertilizer every 23 weeks springfall, none in winter.
  • Regular welldrained commercial potting soil is fine. Repot into fresh soil each spring.
  • Older, larger specimens can simply be top-dressed.
  • Prune back its size to onethird or half in February March.
  • Pinch tips of new growth to keep plants bushy as it can be monitored.
  • Propagate by cuttings.

The primary reason lemon verbena is grown is for its culinary uses. One of the most common uses of the fresh leaves is to add flavor to the tea, hot or iced. This can be used if lemons or lemon juice is not available. It can also improve the flavor of some of the less tasty herbal teas. The leaves can be frozen in ice cubes and added to drinks that way to add a festive and unique look to your drinks. Additionally, finely chopped lemon verbena leaves can be added to a large variety of things to add lemony flavor, including muffins, salad dressings, marinades and cakes. It can also be used as an acceptable substitute for lemongrass in recipes that call for it, mainly Asian recipes. For optimal flavor, the leaves should always be used fresh or lightly cooked.
