Corydalis fumariifolia ssp. azurea


Add to wishlist Remove from wishlist
Sought after and desirable spring ephemeral from the cold forests of northern Japan. This bulbous species - think Corydalis solida for comparison - is one of the best of the blue flowered species in the opinion of the UK's national collection holder of the genus. A single flowering size bulb of this gem but they multiply!
