I don't she is selling tubers still. Has a nice website with lots of pictures for reference. I remember this discussion from last year. She collected all the pretty ones cut flower types, which are not high volume, easy to store, tuber makers. So it is very hard to bring some of them to market in scale unless they are like swan island and grows thousands at a time across many acres. And it created a frenzy.
Like that's why for myself I was/still am so annoyed with my voles / moles this year because its taken my literally 6 years to collect what I have. I had the foresight to have a backup of just about every single tuber and replanted in 1 gallon pots sunk in the ground and those are doing well. So fingers crossed i do not have to shell out $3,000 for 400 tuber replacements lol.
Whenever there is a seller I know going into the sale I am only going to get 1 or 2 tubers of say a BQ troy P and a "lakeview peach fuzz" those usually sell out instantly. I am sure Amanda has all the data of which ones sell out and which are the most searched on dahlia addict.
