Corydalis flexuosa ‘China Blue’ has incredibly intense blue flowers – few other plants have flowers of such a gloom-piercing blue, which ranges from almost turquoise to mid china blue. Grow three or five plants in a group to make the greatest effect in a larger garden. Beautiful plants for adding spring detail to a woodland garden, or a humus rich border in the shade of shrubs.
