#yellow corydalis

I almost forgot, trusty old Heuchera ‘Stainless Steel’ is blooming now too. And hanging out in the background is yellow corydalis.

Edit: the variety is actually Pewter Veil.

Often found growing out of the cracks in old walls and pavements is Corydalis lutea (yellow corydalis, rock fumewort). This clump-forming, evergreen perennial is a garden escapee and produces clusters of bright yellow flowers from late spring into autumn in a sheltered site.

Yellow fumewort (Corydalis flavula), also referred to as yellow corydalis and yellow harlequin, is a graceful perennial herb with clusters of small but brilliant yellow flowers that that really stand out from the early spring leaf litter. A pioneer species closely related to Dutchman’s breeches in the fumitory (Fumariaceae) subfamily, the plant clumps in disturbed areas along forest margins and wooded paths, often in close proximity to its kin. Yellow fumewort’s wispy, fern-like foliage is very similar to the deeply-dissected, compound leaf structure of Dutchman’s breeches, sometimes leading to mistaken identification. The plant’s distinctive lemon-yellow flowers feature two protruding “lips”: an upper petal with a wrinkled crest and toothed wings; and an inward-curving lower petal with toothed edges. Yellow fumewort has suffered serious decline of some parts of its range due to habitat loss and inadvertent “trampling” by hikers along trail edges. The photos above were taken along the Mon River Trail.

Originating in the Alps, the perennial Pseudofumaria lutea (yellow fumitory, rock fumewort, fumitory, fumewort, yellow corydalis, Corydalis lutea) has become naturalised in the U.K. This plant thrives in the crevices between rocks with a moist but free-draining soil in full sun or semi-shade. Here it has seeded in church steps and walls.
