Corydalis ‘China Blue’ – Chinese Blue Corydalis
Corydalis ‘China Blue’ is a beautiful and delicate perennial prized for its soft, fern-like foliage and elegant sky-blue flowers. Flowering over a long period from spring through early summer, this graceful plant adds cool colour and fine texture to shaded borders, woodland gardens, and container plantings.
Reaching around 30–40 cm in height with a spread of 30–40 cm, it forms attractive mounds of finely divided blue-green foliage. Above this airy foliage, slender stems carry clusters of tubular blue flowers that gently nod in the breeze, creating a light and natural appearance in the garden.
This variety is particularly valued for its unusually clear blue flowers, which bring a refreshing colour contrast to shaded areas where many plants tend to flower in whites or pinks. Corydalis ‘China Blue’ works beautifully planted alongside hostas, ferns, hellebores, and other shade-loving perennials.
Corydalis thrives in partial to full shade and prefers cool, moist, well-drained soil rich in organic matter. In favourable conditions it can flower for many weeks, especially if the soil is kept consistently moist during warmer weather.
Removing spent flower stems can encourage continued blooming and help keep plants looking tidy throughout the season.
Flowering Period
April – May: Flowering begins, delicate blue blooms appear above fresh foliage
May – June: Peak flowering with continuous clusters of blue flowers
Summer: Flowering gradually slows while foliage remains attractive
With its soft foliage and elegant blue flowers, Corydalis ‘China Blue’ is a wonderful choice for bringing subtle colour and woodland charm to shaded garden spaces.
