I ordered them last year - for the first time- for zone4.
it was warm early last year... i got mine in June, and i think within 2 weeks they were coming up... i'd have to go back and look at image. I think by mid-July, they were stunning, until Sept -- when it started getting into the 50's.
from what i understand, it has to do with the ground temps.
and as i just placed another order for this year... i would never hesitate ordering from Bill.
I have heard 'the big box stores' -- you just dont get the same results.
YAY Ce Ce.... I think your DH will be happy with your purchase... isn't he a EE guy anyways??
