I really didn't get any blooms this summer, however the ones that are blooming now look just like your late pictures. Maybe it's natural?????

I didn't get any blooms this year from mine until recently and usually it's covered with blooms from May to Nov. - very strange

Very pretty Granny! Mine look just like her late one, except one plant which had gone single, wide open good colors, but not an attractive dahlia to me. That will get composted.

Love those colors- vivid!

I just want to add that Who Dun It is a tuber producing monster. I am GLAD that one plant of it went single so I don't have to bothing to dig it up. There are so many tubers I'm tossing them with reckless abandon.

ah.., the posting that lives on forever. (2005)
Yup, 'Who Dun it" has made a buncha good tubers for me also. And every single cutting that I took in the Spring produced a decent plant. Now that I've said it out loud, the dang things will probably rot during storage. It's true, it's true. That's what happened with 'Gay Princess' this past Winter. Well, almost true. I shared quite a few with other gardeners, theirs survived and mine didn't.
