As far as daylily plants growing in Canada, Mick and Lanny Morry could be a good source of information about growing southern-bred ones. They are very willing to share their opinions about daylilies. While I know that climates vary greatly in different parts of Canada, the Morrys and other Canadian growers could give you their observations concerning the hardiness of specific cultivars. If it makes you feel any better, there are certain daylilies that do not thrive in NW GA. As far as seeds go, there seems to be many different opinions as to hardiness genes being passed on to hybrids from their parents.
