A member of the Papaver (poppy) family, Corydalis ‘Porcelain Blue’ produces flowers for the majority of the year, typically only falling dormant in late winter.

Its soft blue-green foliage has a finely divided fern-like appearance bearing flowering stems of a delicate light to midblue.

In 2005, Hillier Nurseries started testing and collecting a large range of Corydalis species.

Corydalis are loved by pollinators, so it was only a matter of time before natural hybridisation occurred and soon distinct characteristics began to emerge.

One particular new cultivar, Corydalis ‘Porcelain Blue’, with its beautiful blue flowers and sweet honey-like scent, stood out.

Despite its fragile appearance, Hillier said it is surprisingly robust.

It is being launched at RHS Chelsea Flower Show 2017 and entered into the RHS Chelsea Plant of the Year competition.
