I think my daylilies do better if I put them in a pot on my patio first (and water as often as necessary) then plant them in my garden a few months later. (I am planning on Labor Day Weekend) I learned the hard way NOT to overwinter them in pots in my zone - even though they were in large pots (I recycle plastic kitty litter bins)
And I agree, as much as possible plant orders together. Sure helps when trying to figure something out the next year if a plant was mislabeled. ~Jan
