Thanks, gardenglory
I think I see what you mean ... to know a seller's climate zone and see if it matches up before ordering. I like the southern sellers, since my 8b seems to track pretty close (oddly, they track even better than local, but still very different, hybridizers' zones).
So, I'll buy and plant my EE/E/EM's this fall and they should be ready to scape and bloom next spring. Meanwhile, I'll order M/ML/L's to arrive for planting before May, and they should be ready for scaping and blooming by their intended season.
Now if I could just stop my wished-for daylilies list from growing Bigger every time I try to make it Smaller ...
... makes it very hard to put in an order ("oh, but what if.... or, that one too ... hmm, can't let that one pass me by...")
