Some plants seem to take much longer than others to really reach their potential and actually show what they are capable of. After four years my named cultivar 'Gypsy Rose Lee' has some scapes with 5 branches, something I have not seen on it before.
Still if a person has limited space for seedlings, would they better off watching a plant for an extra year or two, or if a plant does not show immediate potential, replacing it with something newer? I guess that is a decision each of us has to make about our seedlings, but I suspect it is a little of both even with the huge growers that do thousands of seedlings a year. I suspect that sometimes there are just a few plants that for some reason has that little extra something that allows it to be keep that extra year or two.
