Expert tips
The key tip
This little Veronica needs well-structured, moist but drained soil, and full sun for dense flowering. Pinch young plants in March to encourage compact, bushy growth.
The common mistake
Exposing it to shade or overfeeding with fertilizer: it becomes leggy, flowers sparsely, with long fragile stems.
The pro's trick
After flowering in June, prune lightly (remove spent flowers and 10 cm of stems): this often triggers a small second flush of blooms in September, especially in mild climates.
Care
Exposure
Fragrant speedwell thrives in full sun for optimal flowering and better fragrance. It also tolerates partial shade, but will produce fewer flowers. Place it in a bright, airy location, away from overly shaded areas.
Watering
Keep the soil moist but well-drained, particularly during the growth and flowering period. Water regularly in summer, especially in hot weather, without allowing water to stagnate at the base. Reduce watering in winter if the plant is semi-evergreen.
Soil and planting
Speedwell prefers well-drained, medium-textured soil that is lightly fertile. Enrich the substrate with compost at planting time. Avoid overly compact or waterlogged soils that promote root rot.
Pruning and maintenance
Prune lightly after flowering to maintain a compact shape and encourage branching. Remove spent flowers to extend the flowering period. In late winter, cut back dead or damaged stems if the plant is semi-evergreen.
Fertilization
Apply balanced fertilizer in spring as vegetation begins. A light feeding every 4 to 6 weeks during the flowering period stimulates flower production. Avoid excess nitrogen, which encourages foliage at the expense of flowers.
Diseases and pests
Speedwell is generally robust but can be affected by powdery mildew in excessively humid conditions. Space plants well to ensure good air circulation. Watch for whiteflies or spider mites in overly dry atmospheres.
Did you know?
The Veronica genus has fascinated botanists for centuries: speedwells bear evocative common names such as "Speedwell" in English, referring to the speed of their spring flowering. According to tradition, fragrant speedwell was appreciated by Victorian gardeners for its delicate fragrance and airy appearance, often featured in small indoor bouquets.
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.
