Care
Exposure
Set your striped clover in full sun for optimal flowering. It also tolerates partial shade, but growth will be less vigorous there. Prefer a well-cleared and airy location.
Watering
Water moderately, especially during summer drought periods. Once established, striped clover is fairly tolerant of drought thanks to its deep roots. Avoid excess water which would promote rot.
Soil and planting
Striped clover adapts to poor and well-drained soils, even chalky ones. No rich organic matter is needed; it prefers austere conditions. Light, gravelly soil suits it perfectly.
Fertilizer
No fertilizer is recommended for this pioneer plant. Being a legume, it fixes atmospheric nitrogen itself through its roots. Excessive fertilization would slow its natural growth.
Pruning and maintenance
No pruning is necessary. Let the plant develop freely; it will self-seed naturally if flowers are left in place. Light intervention can be done after flowering if the plant becomes invasive.
Diseases and pests
Striped clover is not very prone to disease. In overly humid conditions, root rot may occur. No specific treatment is generally required; simply ensure good drainage.
Did you know?
Striped clover is a pioneer plant appreciated by agronomists: by enriching the soil with nitrogen, it prepares the ground for other species. In the Middle Ages and Antiquity, wild clovers were key elements of crop rotations, allowing soil fertility to be restored without intensive ploughing.
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.
