You're very welcome, and thanks for the acorn
There are some things we know about daylily seeds, some things we don't know and some things we can guess at. Because they can behave differently under different circumstances there often seems to be contradiction. In some cases rather than a certain technique actually doing something, the reality can be that the seeds germinated in spite of rather than because of it. Same thing if the seeds were non-dormant for whatever reason, someone may go through some complicated procedure and think it worked when the seeds would have germinated just as well if planted without any pre-treatment. Bottom line is that if they don't all germinate within one to three weeks of planting at room temp they would have benefited from stratification.
