F1 Hybrid question
I think this might be the right forum for my question, and please excuse it if it seems silly to non-beginners like yourselves:
If I buy a tray of F1 Hybrid bedding violas, all very much alike except for one which is completely different, is it likely that this plant is a 'throwback' of some sort genetically, or was simply placed by a worker in the wrong tray? What would be the likely reason? Or did some wandering pollinator get to one of the mother plants before the hand-pollination took place?
Or maybe F1 Hybrids are not all hand-pollinated, am I wrong about that? I am curious because I bought some F1 hybrids, the store had trays and trays of them, all very much alike, but in this one tray, a totally different plant as to colour, habit, everything.
