Corydalis sempervirens is an attractive biennial native to rocky, shallow-soil sites and cooler climates. It is easy to start from seed and has light to dark pink tubular flowers with yellow tips and greenish-blue leaves. Being a biennial, it will have basal rosettes at ground level the first year and flowering plants the second year. It could fill in any bare spot in a sun or semi-shade garden quite quickly.
Pale Corydalis can be propagated through division and seeding and does best in dry, sunny to partly sunny areas of slopes, woodland edges, rocky or sandy soils, but where the air temperature is not overly hot, as this is a plant for cooler environments.
