Care
Light and climate
Eyebright thrives in full sun to partial shade in cool, well-ventilated environments. It loves mountainous or high-altitude areas and dislikes excessively hot, humid summers. Plant it in a location with good air circulation to prevent fungal issues.
Soil and planting
Choose well-draining, rather dry soil that is poor in organic matter and slightly acidic. This plant doesn't demand rich soil and adapts well to rocky or stony terrain. Sow in autumn or early spring depending on your climate.
Watering
Water moderately, especially during germination and early growth phases. Once established, eyebright tolerates drought well and only needs watering during prolonged periods of intense heat. Avoid excess moisture, which promotes disease.
Nutrition
Eyebright is an undemanding plant that generally requires no fertilizer. Natural, balanced soil is sufficient. Overly rich fertilizer could promote leafy growth at the expense of flowering.
Pruning and maintenance
No pruning is necessary for this small herbaceous plant. Let it develop naturally and simply remove any dead or damaged parts if needed. After flowering, you can let seeds disperse to encourage a new generation.
Diseases and pests
Eyebright is generally very hardy and seldom affected by disease. Focus on good ventilation and avoiding stagnant moisture to prevent rot or fungal infections. Pests are rare on this species.
Did you know?
Eyebright was long known by the poetic names 'spectacle-breaker' or 'herb of the eyes' due to its traditional reputation for promoting eyesight and eye health. Although lacking solid scientific backing, this reputation led it to be used in popular phytotherapy since the Middle Ages, particularly in the Alpine and mountainous regions of Europe.
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.
