2) Does each individual registrant determine this info for the plant they are registering based on when it blooms in their garden? This would seem to cause several problems. It seems the ranking would depend on the plants already growing in your garden. If you specialized in extra early plants and all the plants you grew were "extra early" that would throw off the normal midseason timing, and if you specialized in extra late and all the plants you grew were" extra late bloomers" then that would also throw off the Midseason timing.

Yes each individual registrant determines this info for the plant in their garden. This is usually the only place it is grown so that is all they have to go on. At some point in time these hybridizers have probably grown plants from all the different bloom times so I'm sure they know when peak bloom is in their garden. For example and let's assume I have had normal winter conditions.... so if my peak is about mid-May and ALL my plants bloomed the last week in March or the first of April then I know that these are Extra Early or if ALL my plants started blooming mid-late June I would know they are all Very Late bloomers since I already know when my peak season is.
But to answer your question in a garden setting if you were to grow all Extra Early plants then yes your peak season would actually be different than others because of what you are growing.
