Leftwood - good point. If I can get them to grow for another year or two, I might have some seeds in the bank.
Abhege - thanks for posting those pics. I do have one seedling for comparison.
Caroline - I hadn't thought about the blooms being day-light sensitive. We did have a cloudy, cool spring last year when my two plants went in. They got rather tall and lanky and were leaning quite a bit.
Thanks all for your advice.
