I looked for your husband's grandfather in the originators part of the classification of dahlias handbook & couldn't find any introductions. Do you know the names of any of the dahlias he introduced? It might be easier to find them if we knew their names.

PlantLady2, thank you for your post. Rolla's dahlia's are listed below.

Zufall's gold
Zufall's Nancy
Zufall's Joy
Zufall's Jeffery
Zufall's Debbie

I truely do appreciate any help you can provide me!

I checked the Big List & couldn't find anyone selling the Zufall introductions but I did find them in the 20 year Composite Listing of dahlias so there might be a chance that someone out there still grows some of them but doesn't show or sell them. You should ask on a couple of the other dahlia message sites like the one below. Good luck & sorry I couldn't find much out for you.

Here is a link that might be useful: Dahlias

Deborah,

My name is Abby Tappendorf, I am the great-granddaughter of Rolla Zufall (my mom is your husband's cousin, Peggy, daughter of Virginia, Rolla's Daughter). This is my work's HOUZZ account, I don't have one of my own.

I am starting a Flower Farm this year and I would love to offer the Zufall Hybrids! Did you ever hunt them down?

Any information would be fantastic!

Thanks,

Abby
