hi! I'm in zone 5 and I'm happy to report that Dragonfly Dawn has thrived for me! She has survived brutal winters recently, lazy year with little snow cover. Dragonfly Dawn multiplies well for me and is currently reblooming. I use the pollen successfully, and set pods with her as well. Her seeds are always among my 'keepers'. I have several seedlings form her crossed with broken pattern pollen and had nicely patterned blooms😍
