Astrantia major 'Primadonna'
Apparently slugs dislike Astrantia. We've yet to test this out but these could be a good companion plant for hostas - we'll let you know. Meanwhile, Primadonna is a very good choice as low growing ground cover for damp but well drained areas in partial shade.
The wine red bracts are borne in profusion on branching, wiry stems from mid-June onwards. They thrive in heavy clay and almost anywhere the soil stays reliably moist but not waterlogged.
Astrantia dislike being transplanted and will sulk if the roots are disturbed. They will recover after a couple of years.
