Corydalis 'Rainier Blue'


Add to wishlist Remove from wishlist
A fine Corydalis collected by Hinkley in Sichuan and there is speculation that it might be a flexuosa x elata hybrid. What we know is that it is an excellent garden plant with loads of light blue flowers which puts on quite the show. Best in light shade or morning sun and moist.
