I read about agrimony last night in a book about medicinal plants. It seems like a nice plant to have in the yard, even if one is not using it for medicine.

Can I grow it in zone5, upstate New York?

I found a source for plants, across the country in the Puget Sound area. I doubt that tiny plants could survive the journey across country in summer.

Can I plant seeds now or do I need to wait and wintersow next season?
