Aloysia triphylla

Deciduous shrub growing to approximately 3m by 3m when planted in the garden and up to 1m when planted in containers. Plants are evergreen in warm winter locations but deciduous in areas where freezing temperatures occur.

Rough, aromatic leaves. Small fragrant white flowers are produced in summer.

Prefers full sun and well-draining, fertile soils.

Always choose healthy, well-grown plants and plant after autumn rains. Before planting, ensure the root ball is saturated and remove the planter pot with minimal root disturbance. Trim any broken roots and plant at the same level as in the container. Dig a hole twice the diameter of the root ball, press in and water once planted.

Apply mulch annually to discourage weed growth and help maintain moisture. Fertilise in spring with a balanced fertiliser. Pick and dry leaves in summer before pruning. Prune off any diseased or damaged branches after flowering to maintain health, shape and size.

No serious insect or disease problems.

Edible Garden

The flavour of lemon verbena is reminiscent of lemon candy, as it is sweet with strong lemon and no sourness.

Leaves and flowers can be used both fresh and dried when cooking. The leaves are thin and dry quickly after picking. After cutting the leaves, they should be washed and laid flat or hung in small batches. Pick a dark spot with good air circulation or cover lightly with a paper towel. Bunches can be loosely placed in paper bags. It is important to remember to check daily for dryness. As soon as the herbs are dry (when they crackle and crumble in your hand) they should be placed in an airtight container out of the light.

Dried lemon verbena leaves and flowers can be powdered and sprinkled on veggies or fish, combined with other dried herbs to create bouquet garni, or used in baking and desserts. Fresh lemon verbena leaves are used to make sun tea, as well as flavoured sugar syrups, liqueurs and oils. For making dishes where fresh leaves will be eaten (like a pesto), the young leaves are more desirable.
