Wildside Blue Corydalis
Corydalis elata x flexuosa 'Wildside Blue' is a hybrid perennial known for its bright blue flowers and delicate, fern-like foliage. Originating from the mountains of China, it thrives in woodland settings and shaded garden areas. In late spring to early summer, 'Wildside Blue' produces an abundance of tubular, bright blue, slightly fragrant flowers on slender, arching stems above blue-green, finely divided foliage. The leaves form a low, dense mound that remains attractive throughout the growing season.
