My most memorable dahlia was Allen’s Cascadia at the Midwest trial garden last year. It was stunning, and a heavy and early bloomer. I was so excited to grow it this year, but I didn’t get a single bloom and it only made one tuber. Oh well. I’ll try it again next year if that one tuber overwinters.
I haven’t seen anybody post photos of it this year. I wonder if it turned out to be a difficult one.
