Care
Light Exposure
Plant your three-leaved speedwell in full sun or partial shade. It appreciates bright locations for generous flowering. In very hot climates, light afternoon shade will benefit it.
Watering
Water regularly during the spring and summer growing period, keeping the soil moist but not waterlogged. Gradually reduce watering in autumn. Ensure optimal drainage to prevent root rot.
Soil
Prefer light, well-draining soil that is poor to moderately fertile. This plant tolerates chalky and dry soils once established. Adding sand or gravel improves drainage if your soil is clayey.
Pruning and Cleanup
Pinch back stems early in the season to encourage a bushy, branched habit. After flowering, cut back faded stems to extend the plant's lifespan and encourage light re-flowering in autumn.
Fertilizer
A light application of balanced fertilizer in spring is ample. Avoid excess nitrogen, which promotes foliage at the expense of flowers. Poor soils suit this undemanding plant perfectly.
Diseases and Pests
Three-leaved speedwell is generally robust. Watch for powdery mildew in conditions of stagnant humidity. Pests are rare, but excess moisture can promote rot. Ensure good air circulation and impeccable drainage.
Did you know?
Veronica triphyllos owes its name to the characteristic shape of its leaves composed of three leaflets, hence the term 'triphyllos'. Long used in traditional herbal medicine in central Europe, this small herbaceous plant was considered a tonic and diuretic by old herbalists, though it is no longer commonly used today.
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.
