Care
Light exposure
Biscay bindweed thrives in full sun, requiring at least 6 hours of direct daily sunlight for abundant flowering. A south or west-facing exposure is ideal in temperate climates. In shade, the plant becomes leggy and flowers sparsely.
Watering
Water moderately during the growing season, never allowing water to stagnate. Once established, this plant tolerates drought well thanks to its deep root system. In winter, reduce watering considerably.
Soil preparation
Plant in well-draining, light, and even poor substrate: the plant thrives in chalky or sandy soils. Adding gravel or pumice improves drainage, which is essential to prevent root rot.
Pruning and maintenance
Pinch young stems in spring to encourage branching. Remove dead or damaged parts in late winter. A light pruning after flowering can rejuvenate the plant and stimulate reflowering.
Fertilizing
Undemanding, this bindweed needs only light fertilizing in spring. A moderate application of balanced fertilizer is sufficient; excess nitrogen promotes foliage at the expense of flowers.
Health and prevention
This plant is generally robust. Ensure optimal drainage to prevent root rot in case of excessive moisture. Pest infestations are rare under appropriate growing conditions.
Did you know?
Biscay bindweed is a mountain plant native to the Picos de Europa in northern Spain. Although its family, the Convolvulaceae, is renowned for invasive climbing species, this particular species remains compact and well-behaved, making it ideal for rock gardens and sunny slopes where it naturally thrives.
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.
