Aloysia triphylla, Lippia citriodora, lemon verbena
Native to South America, the Aloysia genus belongs to the Verbenaceae family. We decided to include Aloysia citrodora in our collection as it's a plant we like both for its ornamental qualities and aroma:
- it forms an elegant, easy to grow shrub with lovely aromatic lanceolate leaves (lemony smell and taste) and produces long panicles of white flowers in late summer;
- it is a valuable variety in a rockery or pot and can be pruned over the years to form a miniature tree;
- the leaves, harvested in late summer and then left to dry, can be used to make a delicious, calming herbal tea.
In seaside gardens plant lemon verbena preferably in the sun and in a rock garden it likes poor, dry, gravelly soil.
In temperate climates, plant against a wall for warmth and apply a protective bracken mulch before the winter sets in.
In continental climates grow in pots and overwinter in a cold frame.
Prune at the end of winter as soon as the buds appear. Only keep two to three eyes from the previous year's shoots. Remove damaged or untidy stems.
If you grow lemon verbena in a pot, it will need repotting in a mixture of equal parts good garden soil, mature compost and drainage elements (rough sand).
Harvest leaves in late summer before the flowering tops appear.
Overwinter in a frost-free shelter or apply a thick bracken mulch.
