Let me sum up again:
Bloom time is based on the number of weeks of divergence from what is determined to be peak bloom time. Peak bloom time is calculated based on a uncertain percentage of plants blooming in an individuals garden, or upon the time plants bloomed when they used to be grown in an individuals garden? In general when your garden is really pretty, that is peak bloom time?
I am catching on pretty fast to all this daylily stuff.
Of course I am joking, but it is easy to see how a newbie to daylilies is just totally lost when he realizes all the data he took for fact in the data base as he selected his plants after hours of study finally realizes they were all pretty much a myth. He needs ask around locally, see what grows in his area, and then if he wants something new he needs to...buy it and try it!
So, not being a hybridizer myself I see I really don't need to bother much with all that stuff. I just need to get my daylilies and grow them the best I can and hope my garden looks really pretty at peak bloom time.
