A real gem of a plant - purple-blue, dangling bells in summer on very neat wee plants. Spreads very slowly by underground stems. Special, but not at all difficult - free-draining soil which won't dry out too much and sunshine are all it needs.
Dainty enough to be happy in a stone trough or sink. About 7cm (3") high.
Introduced by Alan Bloom at Bressingham and another of my favourite plants.
