A vigorous cultivar with a long flowering period. Large, pale blue flowers with mauve veining, long pointed sepals and coffee-brown anthers. If stems are pruned back lightly in spring (pruning 2) it flowers almost incessantly from May to August. It may also be hard-pruned (pruning 3), but the first crop of flowers will thus be lost - it will start blossoming in July and continue till September. Particularly useful for cultivation on exposed positions, especially against a dark background or plants with yellow flowers or foliage.
