Lemon Verbena

Aloysia triphylla [aka A. citriodora, Lippia triphylla]

Tender perennial; grown as an annual in most parts of Canada

Height 1 to 2 m; spread 45 cm to 1 m.

Herb with stiff, apple-green, willowy leaves and small, pale-lilac flowers in pyramid-shaped clusters.

Try these!

Only Aloysia triphylla is readily available in North America.

Planting

Lemon verbena is best grown from young plants purchased from a garden centre.

How much: At least two plants.

When: One to two weeks after the average date of last spring frost in your area.

Where: Full sun, sheltered; a south facing wall is ideal. Prefers rich, well-drained soil. Space plants at least 30 cm apart.

Care and Nurture

Lemon verbena is easy to grow! It loves heat, but don’t let it dry out.

Harvesting

Harvest leaves throughout the growing season. The flowers are also edible and tasty, but verbena rarely blooms in Canada’s short growing season.

For best flavour: Harvest mature plants: the lemon fragrance and flavour grow stronger with age.

Leaves: Strip leaves from the woody stems with your fingers; discard any tough stalks.

Flowers: Harvest as they appear; clip from stem and use whole.

Preserving the Harvest

Lemon verbena leaves will retain their flavour for years. Dry and place immediately in an airtight jar, and keep the jar in a cool, dark place. You can also freeze the chopped leaves and flowers; use the ice-cube method (see page XXX).

Tips

  • Give lemon verbena the sunniest location you can. The plants respond well to warmth and light.
  • Lemon verbena usually grows best when it is free of competition. However, I like to plant lemon verbena in a pot with 'Dark Opal' basil: the plant's contrasting leaf colours look fantastic together, they like the same growing conditions, and one never overgrows the other.

To Note:

  • Put lemon verbena leaves in the vacuum cleaner bag to freshen the house while you clean.
  • Infuse sprigs of lemon verbena for use in finger bowls.
  • Lemon verbena's essential oils are used in soft drinks, liqueurs, and perfumes. The dried leaves are good for potpourris.
  • Lemon verbena is native to South America. The Latin Aloysia comes from Maria Louisa, wife of Charles IV of Spain.
  • In the film Gone With the Wind (1939), lemon verbena is one of the favourite fragrances of Scarlet O'Hara's mother.
