Basically we do stop making seed on June 1st Old Woman, but I sometimes will make a few late seed if something I want to use is blooming late. The examples I posted are not the norm, most changes to the bloom will be small, what I really look for in a two and three year old seedling is a decent scape, I already have a nice bloom, so I want to see a lot of blooms on a well branched scape and of course it must continue to rebloom.
