That's the way it works with me. Things that aren't supposed to grow here I can grow no problems (zone 7 roses in a zone 5 climate). Things that supposed to be unkillable? They croak within minutes it seems like. I think, also, that every time I get coneflowers in the past, it's always at the one nursery that I have found, through trial & error, I have 50% luck with. They grow their plants in a hydronutrient environment and when you get the plant, they're HUGE, but their root system is soooooo bunched up at the bottom from the way they're grown. I think I'll look for HardyBoy plants next time.. I have good luck with them.
My Golden Jubilee was very dark this year, not golden at all. Of course, it gets only about half-sun, so I am going to move it this year to someplace else. It's never volunteered any seedlings, though. Wonder why.
