Hi, I guess live and learn is what I have done. About 10 yrs ago when I got into collecting I thought they were all lovely. My taste has changed. I now prefer Ufs , big and bright blooms. I still love a fancy, frilly one. I do add to extend my season now. I also look for high bud count, strong scapes. I hate a flopper or one that blooms down in the foliage! In the last 18 months I have culled about 100 that I was not so pleased with.
Now what stays is first of all what I think is beautiful, but it has to make the grade to be a keeper. I love the database here on ATPs because we have so much info at our fingertips.
