Hillier™ Porcelain Blue Corydalis

Corydalis flexuosa 'Porcelain Blue'

This exquisite woodland plant displays vibrant aqua blue flowers in spring, repeating profusely in late summer to fall. Finely-cut blue-green foliage may take on a bronze cast in the heat but does not suffer from summer dormancy like others. Great for a shaded bed, or spilling from a container or over a wall. An herbaceous perennial.
