Corydalis curviflora rosthornii ‘Blue Heron’
Blue Corydalis |
USDA Zone: 6-9 |
Plant number: 1.167.250
Just recently collected in China, this outstanding selection may be the best blue-flowered Corydalis ever introduced. It forms a mound of ferny blue-grey foliage, topped for several weeks in the spring with clusters of intense sapphire-blue fragrant blooms. Give this a cool, shady position with regular moisture. May go dormant in summer if kept too hot or dry. Habit appears to be distinctly clumping rather than spreading, with little or no self seeding. Performance over a wide range of climates is not yet known. An absolute gem for the moist woodland garden. Collected in Sichuan, China by Dan Hinkley of the famous Heronswood Nursery in Washington State.
