touchofsky said:In the case I was mentioning, I took a look at registered child plants, and one registered child was yellow and two were cream, so it would seem there could be a yellow one or cream one pop up, even though the parents were both a deep pink.
@touchofsky Some of registered child plants could also have been from bee pods (unintended/unknown pollinations). There is no guarantee that any daylily hybridizer uses "safe" hybridizing techniques unless they state that they do so.
If you look at the ancestry of the registered parents then that may provide evidence for whether yellow or cream coloured seedlings are reasonable from the particular cross of the two deep pink parents. In some cases the ancestry of both deep pink parents might suggest that yellow or cream seedlings were possible while in other cases it might suggest that they would be improbable.
