Welcome Kat! Lot of good people here,glad you found us.
I have ordered from Wild's previously, never had a problem. But you are correct, this past winter was brutal. I too lost some new, and some established daylilies. I also lost a lot of tall bearded iris - and that was surprising. And don't even ask about my digitalis and poppies - all gone.
But I think with plants that there will always be some type of loss, heck 2 years ago I lost a beautiful, stunning, mature maple tree. Budded out then died. Of course, I now have a large daylily bed where that tree once stood, so it's not all bad.
As for height on daylilies, check the plant listings here. Although I love big bold tall daylilies, I also have a few minis because they are so sweet and short.
Check out the other threads, and the porch swing thread. We love to chat, and don't be afraid to just pop in on the conversation.~Jan
