Corydalis ‘Porcelain Blue’ was developed by Hillier Nurseries and made its global debut on our RHS Chelsea Flower Show 2017 garden, where it made a big impression.
The most striking feature of this Corydalis is its electric blue coloured blooms. This is a surprisingly robust garden plant, despite its delicate appearance. The ‘Porcelain Blue’ flowers for the majority of the year typically only fall dormant in late winter. It has a sweet honey like scent, attractive, soft blue-green foliage and bears flowering stems of a delicate light to mid blue.
In late 2020, it received a prestigious Glass Tulip award, held in The Netherlands for Best Garden Plant.
