Leaves 10cm or more wide, deeply divided into five to nine lobes, each with several long, pointed irregular teeth. Flowers in a compact inflorescence, opening one or two at a time, 4cm across, shallowly cup-shaped, deep blue through paler blue or lilac to pink and white. Widespread through most of Europe including Britain, and through Asia into China. Easy in an open position and self-seeding freely. This variable plant has several named cultivars including double forms and it also hybridises in gardens with other species. Too large for the rock garden. A dwarf alpine form from central Asia has been named G. regelii, but it is now doubtfully in cultivation.
