This is a difficult plant to grow in my climate (Boston Z6a). I haven't succeeded in wintering it over.
The trick in grow...Read Moreing all the blue corydalis is exquisite, rock-garden type drainage, consistent moisture, and protection from strong sunlight.
This species isn't hardy north of Z6, and it hates the hot humid summers of the southeastern US.
The easiest blue corydalis to grow in my climate is the hybrid 'Craigton Blue'.

I bought nice healthy plants online and tried again. They got smaller and smaller over the season and again died even though I put plants in different areas in my garden. That blue is so beguiling that I am going to try again this year. It is so strange as I have other corydalis, yellow and white, that happily multiply become more and more abundant year by year.
Hopefully, someone will add some comments to help me figure out the problem. I find none in local nurseries, but someone commented here in their success in Norristown, right down the rood from me..

I bought this "Panda" one (the second-pictured Corydalis), but it came with no 'instructions' to guide me, and didn't think to check...

Updated May 30, 2006: Thought it had entered "summer" dormancy toward the end of last month. Unfortunately, upon closer inspection, the roots have withered and are definitely no longer viable... not at all heat tolerant, it seems. :-(
