Corydalis cava is a species of flowering plant, native to moist, shady, woodland habitats throughout most of mainland Europe, although commonest in central and southeast Europe. Its range extends from Spain in the west to Ukraine, Belarus and the Caucasus in the east and as far north as Sweden. It is absent from (though may sometimes be found in a naturalised state in) Iceland, the UK, the Netherlands, Norway, Finland, Russia and Greece.

Corydalis cava grows 15 cm (6 in) to 30 cm (12 in) tall. It is a spring ephemeral—foliage that grows in the spring dies down to its tuberous rootstock in summer. It has long-spurred flowers which appear in spring. The flowers may be mauve, purple, red, or white.

The seeds contain an elaiosome that attracts ants, which transport the seeds into their ant colony. This seed transportation is called myrmecochory. [Wikipedia]
