Corydalis solida, or fumewort, is native to moist, shady habitats along rivers. It is an ephemeral, with
foliage that appears in spring and dies down to its tuberous rootstock
in summer. It has narrow, long-spurred flowers that show color variation, and
may be mauve, purple, red, or white.
Like some other plants already described on this blog,
the seeds are disseminated thanks to ants.
This plant, in particular
the root, is toxic: it contains alkaloids (notably corydalin), high dose of
which are dangerous for
the spinal cord. The plant is used in phytotherapy against Parkinson disease.
