Expert tips
The key tip
Verbena officinalis grows almost anywhere but flowers best in full sun and poor, well-drained soil—its toughness comes from asking little of the earth, though it does gradually decline if pampered. Deadhead spent spikes to keep blooms going until October.
The common mistake
Giving it rich, moist soil thinking you're helping: it gets leggy, weak, and rots instead.
The pro's trick
Sow it in September on bare soil: it germinates in fall, overwinters as a sturdy seedling, and flowers faster the following summer.
Seasonal watch
Extended autumn: if September–October brings heavy rain, cut back watering to prevent root rot before winter sets in.
Care
Light exposure
Wild verbena prefers a sunny location to bloom generously. However, it tolerates partial shade, where flowering will be less abundant. Plant it in a bright, open spot.
Watering
Water regularly during the first year to establish a good root system. Once established, this plant is moderately water-hungry and resists drought well. During summer, keep the soil slightly moist without excess.
Soil
Verbena adapts to most soils, provided they are well-drained. It hates waterlogged conditions. Poor to average soil suits it perfectly, without need for major amendments.
Pruning
Remove spent flowers regularly to prolong blooming. In late winter or early spring, cut stems back to 15-20 cm to encourage compact, bushy growth. This plant regrows vigorously.
Fertilizing
Undemanding, verbena only needs light fertilizing in spring. A moderate feed in late spring supports flowering without excess. Avoid overfertilizing, which would weaken the stems.
Pests and diseases
Very robust, verbena is rarely affected by serious diseases. Watch for powdery mildew in overly humid, waterlogged conditions. Aphids may occasionally visit, but cause no serious harm to an established plant.
Did you know?
Official verbena has been known since Roman antiquity, where it was considered a sacred plant and used in rituals. In the Middle Ages, it featured in most European medicinal gardens, renowned for its soothing properties. Its name 'verbena' derives from the Latin 'verbena,' a term that already designated sacred herbs.
Where to buy it
Plant in spring or early autumn, avoiding spells of intense heat. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, April, May, September.
