Corydalis White Knight is a very robust plant with large pure white flowers and fine dissected foliage.
Cultivate soils to a depth of 15cms and plant bulbs as per the growing information below. Corydalis like a humus rich and free draining. Therefore in heavier soils such as clay, cultivate the top layer of soil and add grit and well rotted humus. This will provide the drainage that they need. They naturalise really well and will spread out to cover a wide area. These are a lovely group of bulbs that are ideal to grow in semi to full shade. Ideal in the borders/garden or in containers.
Remember to feed well during the leaf and flowering stage to ensure they grow and bulk up well for subsequent years growth. In cold winters mulch well over winter to protect from the severe frosts.
Small specie bulbs like these will benefit from using bulb starter when first planting although of course they will flourish without it as well.
