The young plant did not withstand the journey well despite suitable packaging. The only shoot was broken, I hope the plant will regenerate. I have tried to grow this plant several times without success.

Description

The Corydalis flexuosa, or Chinese corydalis, is an excellent shade ground cover that forms dense mats with electric blue flowers with white bases.

A compact perennial with spreading habit, the Chinese corydalis is a hardy plant with leaves composed of three ovate and deeply cut leaflets, light green tinged with purple, 15cm (6in) long. In spring, the 4-petaled tubular flowers with a spur, bright blue with white base, 2.5cm (1in) long, are carried on slender, erect stems.

Native to wooded areas in China, Corydalis flexuosa prefers well-draining, cool and acidic soils in partially shaded positions. Avoid compact and overly moist soils. Beware, the plant goes dormant in very hot summers.

Corydalis flexuosa is ideal for rockeries, borders, shady containers or ericaceous beds paired with ferns or tiarellas.

Planting and care
