Does this seem like accurate info to send to folks looking for broken down/open center stock? I think it's all true as far as it goes. I could go into how they don't meet pretty much anyone's breeding goals and the social aspects of dahlia breeding, but that seems extra.
"Almost certainly it is a fully double variety that has "broken down" which is the term for when dahlias lose the genetic information to form enough petal rows to cover the pollen center, or that was a bloom from very late in the season when there was not enough solar energy to form a bloom with enough petal rows to cover the pollen center.
Your best bet would be to locate the person who grew this bloom and see if they will share a tuber.
Breeding dahlias involves discarding large numbers of seedlings that look like this. That doesn't mean they are bad or that it's wrong to like them, it's just the reality is that if a breeder kept these, they would quickly fill up their growing space and have to stop breeding. So if people breed dahlias, they cull the messy, open-center seedlings, and if a person doesn't breed dahlias, they will rarely see blooms like this and if they do, they won't have names or be offered for sale."
