I've been keeping an eye on Waunakee Sunsets - everyone (including Chuck Acker) say it is so variable and you know what? It is! I try to keep photos of all of them to compare. Yours is interesting, and different from the other few photos I have. I know one of my other pics is from Russell.
I finally have one, I got it as a replacement for something that bloomed out incorrectly. It is a small seedling though so will be a while before I can compare my own to all of yours!
love the Lutz Roulke,the Barbera Lee Ann is nice also. It may be darker next year when it gets bigger. The cool weather helps the colour also. i have a few that are different also. They all seam to be different, The best I have seen is from Chuck Aucker
