Aloysia triphylla (Lemon Verbena) is a wonderfully aromatic shrub grown for its narrow, glossy green leaves that release a strong lemon scent with the lightest touch. You can use it in containers near patios and walkways where the fragrance is easy to enjoy, or tuck it into an herb or sensory garden for quick harvests. In warm climates it can be a permanent landscape plant; in colder areas it is commonly grown in a pot and overwintered indoors in a bright, cool spot.
Give your plant full sun for the best growth and strongest fragrance. Plant in a well-drained, fertile mix and water deeply, then let the top of the soil begin to dry before watering again. Good drainage is essential, especially during cool weather. If you bring it indoors for winter, expect leaf drop; keep it on the dry side and provide as much light as you can.
At maturity, this plant typically stays in the 36-48 inch height range in containers, with a modest spread that fits well in smaller spaces. Pinch or prune the tips during active growth to encourage branching and a fuller, bushier shape. In early spring, cut back leggy stems to refresh the plant and promote vigorous new shoots.
From mid to late season, small white to pale lilac flowers may appear and can be lightly fragrant, but the foliage is the main show. Harvest leaves as needed for teas, desserts, fruit salads, and other culinary uses, and enjoy the clean citrus aroma all season long.
