A charming perennial variety originating from Japan. Graceful, bell-shaped, deep violet-blue flowers edged in pale mauve are borne incessantly from June to September. Stems don't twine round supports, but they can lean against them. They can be either stimulated to grow higher with the help of some string or wire, or we can let them scramble at ground level. Ideal for scrambling through perennials and shrubs. It can be grown in large containers. Makes good ground cover.
