Cultivated in gardens since the middle ages, Astrantia are grown for the beauty of their intricate pincushion flowers, encircled by ornamental papery bracts they are held on strong wiry stems above decorative, deeply divided mounds of foliage. Not only are they an integral part of the cottage graden look, they fit very well in more contemporary designs and also go very well with ornamental grasses.
The flowers are excellent for cutting, either fresh or dried and the plants are rabbit resistant. They grow in any reasonable soil, full sun or partial shade will both give good results.
As a rough guide planting Astrantia as ground cover – 4 plants per square metre is adequate with a little patience, 6 will give better coverage and 9-12 will make a weed supressing carpet very quickly.
