If a seed has in its genetic history a need to dry up first, and then get wet again with fall rains ( which would occurr naturally in a Mediterranean type climate like mine here in the S.Hemisphere), then it makes sense to dry out seeds of daylilies and rehydrate them later. By now, like it happens with so many highly modified cultivars in roses, irises, true lilies etc. the genetic complexity is enourmous. So it is very difficult to tell apart which option will hold true universally. With such complex backgrounds, extrapolation to universal solutions is too risky. That doesn't mean that a systematic experiment shouldn't be conducted. When it comes around cultivars I would solely accept the validity of results if restricted to the chosen cultivars. The remainder ( which will be thousands) will still remain in the realm of inferred speculation.
