Care
Exposure
Place Orlaya grandiflora in full sun to encourage abundant, compact flowering. It also tolerates partial shade but flowers less generously. Avoid dense shade, which slows growth and reduces flower production.
Watering
Water moderately during growth, allowing the soil to dry slightly between waterings. Once established, this plant is very drought-tolerant and requires only occasional watering. Avoid excess water, which promotes rot and fungal diseases.
Soil and planting
Prefer light, well-drained, chalky soil. This species appreciates poor to moderately fertile soils and dislikes waterlogged conditions. Enrich the soil only slightly before planting; overly rich soil encourages foliage at the expense of flowers.
Fertilizer
Apply balanced, highly diluted fertilizer in spring if the soil is poor. Under normal conditions, no additional fertilization is needed. Excessive nitrogen application slows flowering.
Pruning and maintenance
Pinch young plants to promote compact, bushy branching. Remove spent flowers to extend flowering. At the end of the season, leave a few umbels in place if you want natural self-seeding.
Diseases and pests
Orlaya grandiflora is generally robust. In overly moist soil, watch for root rot and fungal diseases. Aphids can occasionally affect young shoots; increase air circulation and water in dry weather.
Did you know?
Orlaya grandiflora, also called 'white lace' because of its delicate, airy white umbels, was once used in Victorian flower arrangements. Its finely toothed flowers give it a remarkable lightness, ideal for creating 'white clouds' in contemporary Mediterranean gardens.
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.
