Appearance & bloom cycle

Fairies'-thimbles grows into diminutive tufts just 5-10 cm tall, spreading via underground rhizomes to 30 cm wide. Leaves are tiny (0.5-1 cm), spoon-shaped and glossy green - remarkably elegant compared to larger bellflowers.

The flowers are the main attraction - delicate, drooping small bells in soft blue to lavender-purple, approximately 1 cm long. They appear in July-September in astonishing numbers on fine stems. A single plant can produce hundreds of flowers.

Attractive seed heads follow. The plant is evergreen to semi-evergreen.

Ideal location

This plant tolerates full sun to half-shade. Full sun produces the most prolific flowering. Fairies'-thimbles thrives in steep rock crevices, alpine troughs, and gravel beds. It requires perfect drainage.

Soil requirements

Perfect drainage is essential. Create a gravel mix with coarse sand and fine gravel. The plant tolerates poor soils better than fertile soils. Apply no fertilizer.
