A very rare plant indeed. This is one of the few plants with such intense blue flowers and that will also perform well in the garden. Flowering in its first year with 2.5cm (1in) gentian blue flowers, it then produces tubers and springs back to life the following year with an unceasing display of blooms. Wonderful in containers, rock gardens and the border (regardless of soil conditions). Hardy down to -8/-10C. Flowers summer. Height 15-30cm (6-12in.)

When large enough to handle transplant the seedlings to 7.5cm (3in) pots. Later harden off and plant out when all risk of frost has passed 30cm (12in) apart in full sun. Prefers a moist, well drained soil. The seeds can also be sown in autumn in a greenhouse and over wintered. This makes better sized plants for planting out the next spring. The young seedlings usually die back as winter sets in and re-emerge in the early spring.
On heavy soils or soils that lie wet in winter, lift the tubers and store like Dahlias.
