Growing directions
Propagate from softwood cuttings taken in summer rather than from seed, which has poor viability; root cuttings in moist perlite under plastic until rooted. Plant in full sun and well-drained soil; in zones below 8 grow in containers that can be overwintered indoors in a cool, bright spot. Prune hard in spring when new growth emerges from what may look like dead wood — lemon verbena is often a slow riser after dormancy. Harvest leaves any time for intensely lemon-scented tea, dessert flavoring, and potpourri; fragrance peaks just before the plant begins to flower.
