About this plant
Corydalis flexuosa 'Porcelain Blue' is an impressive perennial plant prized for its vibrant blue flowers and delicate, fern-like foliage. Native to the woodland regions of China, it is well-suited to shaded garden areas, offering a long-lasting display of blooms from spring to early summer. In late spring to early summer, 'Porcelain Blue' produces a profusion of sky blue, tubular flowers with distinctive white throats on slender, arching stems above blue-green, finely divided foliage. The leaves form a lush, dense mound that remains attractive throughout the growing season. Versatile and attractive, 'Porcelain Blue' is an excellent choice for woodland gardens, shaded borders, and rock gardens, pairing beautifully with other shade-loving plants like ferns, hostas, and hellebores. Its appeal to pollinators also makes it valuable for supporting local biodiversity.
