'''''Corydalis''''' is a genus of about 300 species of annual and perennial [[herbaceous]] [[flowering plant]]s 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 [[botanist]]s 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 Zone]]s 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 [[larva]]e of some [[Lepidoptera]] species including [[Silver-ground Carpet]].
''Coryd
alis'' contains the alkaloid [[bulbocapnine]], which is occasionally used in medicine.
