I agree that Hemerocallis seeds probably don't need a cold treatment.
However, since I live in a Zone 5 climate (Milwaukee, WI) and don't collect
the seeds until September or even later, I keep the seeds refrigerated to
DELAY germination until spring.
Whether your plants will come "true" from seed depends upon the parents.
If the lily was "selfed" (pollenated from the same flower) the greater the
chance the seedling will at least resemble the parent. The more highly
hybridized the plant was in the first place, the greater the variability.
I'm completely random in my hybridization - just to see what comes up in
the mix. I don't know if Stella d'Oro is a good seed parent or not - some
cultivars set seed readily, others don't. I believe that hemerocallis are
more likely to receive pollen from the same flower than from others, but
unless you hand-pollenate, you can never be sure.
