About

Yellow corydalis is a pretty flower that originally came from the foothills of the Alps in Southern Europe, but now grows wild in the UK, often as an escapee from gardens. A shade-loving plant, it can be found in rocky places and walls, in particular. It flowers from spring until mid-summer.

What to look for

The leaves of Yellow corydalis are much-divided and yellow-green. They form compact, fern-like mounds. The flowers are like small, yellow trumpets.

Found throughout the UK, but rarer in Scotland.
