"Might shop River's when they open." Our judges refresher training was held at River Dahlias. I cruised his first year seedlings and we had lunch next door to one @ of the main fields. I remember when Eugene Kenyon was first starting out growing and breeding dahlias. His mentor was Wayne Shantz who is a "dahlia giant" (he and his wife Eleanor did the ADS classification book for many years) .
Rosie Cooper-Vert is now the farm manager and she is one of those "full speed ahead" non stop people who gets things done.
If we were acquiring new varieties I would definitely buy from them. And he likes to breed fully double orchid types and those are exotic. His Rivers Yellow Snow is a home run, and is a full sized ball dahlia that is a bicolor in yellow and white. It makes so many tubers, all your friends will get some from you.
