Linda, yes the Svenson Gardens I was referring to is in MN.
And yes, Park Seeds was a tc plant and they do seem to take a few years to bloom. They were cheap, but you have to wait:) I probably will not opt for TC again.
My Bartzella has turned out to be a great plant, but I am still waiting for First Arrival. Should be next year to bloom.
I have not seen purple flash before. I like it!
