Read about Corydalis in the Standard Cyclopedia of Horticulture 

Corydalis (Greek, lark, the spur of the flower resembling a lark's spur). Fumariaceae. Hardy plants allied to the Dutchman's breeches.

Erect or prostrate herbs, usually perennially rooted, but often annuals: lvs. lobed and finely dissected in nearly all the species: fls. racemose, often yellow, less frequently blue, purple or rose; petals 4, spurred as in the Dutchman's breeches; stamens 6, in 2 groups.— Ninety species, natives of the north temperate regions. They are all of easy cult. They prefer full sunlight but will grow in half-shade. Prop, by division or seed.

Species
*Corydalis afghanica

Corydalis is a genus of about 300 species of annual and perennial herbaceous flowering plants in the family Fumariaceae, native to the temperate Northern Hemisphere and also southern Africa. Common names include corydalis and fumewort.

It is closely related to Fumaria, and some botanists include it in that genus.

Characteristics - C. lutea

Yellow Corydalis grows 30-38 cm (12 to 15 inches) tall and its gray-green foliage is attractive from spring until fall. The 2 cm (3/4 inch) flowers are borne above the leaves from spring until mid-summer and sometimes later. The species often grows wild in cracks in old walls where drainage is excellent.

How to Grow C. lutea

Yellow Corydalis grows in USDA Hardiness Zones 5 to 10 (average annual minimum temperature –29°C or above); it does best in light shade, but will tolerate both full sun and deep shade. Excellent drainage is vital and the soil should be liberally supplemented with peat moss or leaf mold. Set plants 8 to 10 inches (~ 20-25 cm) apart. New plants can be started by dividing and resetting clumps in early spring after two or three years of flowering or from stem cuttings taken in summer for flowers the following year. To prevent overcrowding, divide clumps after two of three years of flowering.


Corydalis species are used as food plants by the larvae of some Lepidoptera species including Silver-ground Carpet.

Corydalis contains the alkaloid bulbocapnine, which is occasionally used in medicine.
