Is the flower/plant Corydalis an annual or perennial?

And will it grow well in full shade in Southwestern PA.


Please help and thanks in advance
Is the flower/plant Corydalis an annual or perennial?
According to Sunset%26#039;s Western Garden Guide %26quot;Corydalis%26quot; is a perennial. Should grow well in Zones 4-9 %26amp; 14-24, grows in partial shade, likes moist not soggy soil.





Now their zone map shows Zones 4-9 as being the southern parts of Washington state along the Pacific coast and Zones 14-24 would be the southern part of California %26amp; the desert areas of Arizona.





Don%26#039;t know how this would compare with Southwestern, PA but you might be able to do a comparison. Unfortunately their zone maps cover only to Wyoming.
Reply:Here is a web site. Hope this helps you out. If not go to a local library and barrow a flower book from A-Z.

Reply:Both annual and perennial. Corydalis is a genus with about 300 species of annual and perennial herbaceous flowering plants.





What USDA zone/location it will grow in depends on which species you wish to plant, although many are native to temperate areas.





Sorry I can%26#039;t be more specific.





Good luck!loan
