Well behaved types mostly for shade and a good soil though they are flexible! Some can be summer dormant in hot dry weather so don't worry that they've died and mind that hoe...

Since the re-introduction of Corydalis flexuosa to western gardens in 1992 (the CD&R collections) these bright, electric blue herbaceous Corydalis have become much more widespread and better known.  More collections of other species followed and hybrids with Corydalis elata, Corydalis cashmeriana and others (many unidentified) soon followed.  Some of these hybrids are more or less evergreen which is a great help for those gardeners who have found the summer dormant Corydalis flexuosa difficult to manage.  Corydalis elata also introduces a sweet scent.

We also grow a handful of tuberous types of Corydalis which can be grown just like any other spring flowering bulb.  Our offerings are perfectly hardy in the garden and include Corydalis malkensis and some forms of Corydalis solida.
