I'm in zone 7A (some years it's more like 7b) and wondered how northern hybridized daylilies will perform here. From what I understand Southern daylilies don't perform well in the north because of their cold winters. Does that translate to northern daylilies won't do well in warm climates because of our hot temperatures (summer temperatures over 100 for weeks at times)? I'm interested in a few of Culver's daylilies and he's in Canada about as north as you can get.......Maryl

I buy quite a few daylilies from the North and we have some from Canada as well; they do just fine here ( we are zone 8b)

Maryl said: Culver's daylilies and he's in Canada about as north as you can get.......Maryl

I'm not far from him and we are quite a bit south of many parts of the States. Our zone would vary from a 5A to 6A. And the southern tip of Ontario is south of Detroit and zone 6A to 6B.

Used to be, you might look at a daylilies parentage to see if either parent did well for you. I have noticed that fewer and fewer hybridizers list parentage at all.

Thanks Michelle for the encouragement. You too Brian for the geographical enlightenment. Julie: I don't know if I would know from parentage how that related to a daylilies summer tolerance as I don't follow that aspect of it. But I get your point......Maryl

I just won a daylily from David Mussar, ROSEMARY MUSSAR, on the auction and he is from Puslinch, Ontario, Canada. (CDA zone 5b and USDA zone 4-5)

When I lived in Marietta, GA, (zone 7b) I grew mostly northern dormants and just a few southern evergreens. They all grew beautifully!
