Corydalis lutea/Pseudofumaria lutea

Corydalis lutea

Rock fumewort now has a new name and genus, but the RHS still list Pseudofumaria as just a synonym. It is a pretty perennial with foliage like a maidenhair fern which thrives in sun and semi-shade; it can become a nuisance in gardens where it seeds freely into paving and crevices in brickwork - but it has a shallow fleshy root and is very easy to remove.
