Here on the Gulf Coast where we have very little winter and normally plenty of rain, selected seedlings can be very different from the first to second year. There seems to be little change from the second year to the third, but my selected seedlings are moved and lined out each of the three years, so what I'm seeing could be very different from what others farther north are seeing. During a normal year I will flag 35-45 first year seedlings on rebloom from the 2500 planted, I never select a seedling that doesn't rebloom. During the second year 2/3 of these will be culled because of some flaw with the bloom or scape. The third year I am lucky to have a half dozen for introduction in there forth year. All this elimination has happened in three years because of changes in the bloom or plant itself. I destroyed two plants that I had enough to register this year because they were rust magnets at three years old, another had two of the six clumps die from crown rot, none of these problems showed up until they were three years old. You never really know what will happen until they are at least three years old and even after it's a crap shoot.
This is the way things happen here, it could be different else where.
