I always wait 3 to 4 years before I cull seedlings. You are very fortunate Fred that you live in a climate where you get rebloom. We very seldom get it here and I really can't select seedlings for rebloom unless I ship them elsewhere and have someone else watch them for me. I tried that once and the person fell on hard times and sold all of my seedlings without asking me, so I am not likely to ever do that again.
