Plant details

This has intense, gentian blue flowers, 2.5cm (1in) across, but it is not reliably hardy. If you're lucky enough to live in a very sheltered area, it should flower in the first year and then produce tubers and spring back to life the following year, with a good display of blooms. Where it can be treated as hardy, grow it in containers, rock gardens and the border. Otherwise, grow it in a greenhouse.
