From what I understand, and I could be wrong, the resemblance could just be in the height of the plant, the fact that it is evergreen or not, early or late blooming, extended bloom, maybe even reblooming or not. There are probably thousands of combinations at least. But, having no experience in trying seeds and expecting a desired result, I would like to hear from others who have purchased seeds expecting a particular outcome and actually got what they were expecting. Maybe if enough people post we can get some idea of the percentage of success. I just wonder how many people actually buy daylily seed, maybe a lot more than I would expect! I have seen some beautiful daylilies grown from seed, but how much they resembled their parents and how many seedlings it took to get them I have no estimate of.
