Corydalis solida, syn. C. halleri, C. transsylvanica (fumewort), is a species of flowering plant in the family Papaveracae, native to moist, shady habitats in northern Europe and Asia. Growing to 25 cm (10 in), it is a spring ephemeral, with foliage that appears in spring and dies down to its tuberous rootstock in summer. It is cultivated for its deeply divided, ferny leaves and narrow, long-spurred flowers which appear in spring. The flowers show color variation, and may be mauve, purple, red, or white.
