Arlene - That Penhill Yellow Queen is really nice! For some reason, most of my biggest dahlias are yellow. I am just starting to get blooms from Emory Paul this year, and its the biggest flower I have grown and an intense pink. its a wow.
Your maniac doesn't look that different from mine, I think the lighting in my picture makes the center look much lighter than it is.
Karen - I know exactly what you mean. Dividing and storing my tubers has become a major job. I am really not looking forward to it this year, with 50 more than I had last year. I have to admit that I do very little other fall gardening. There have been a few years when I didn't even get my leaves raked until spring. In the fall its usually cold and wet by the time I get around to it all, and I have a lot less free time (and energy) than in the spring.
Selling some of my extra tubers last year was fun though because it gave me some guilt free money to spend on new plants. I am hoping I can get it together to do that again this year.
