If you have been soaking your daylily seeds in a water/peroxide solution and they still haven't spouted after 12 days, what do you do? Most of the time mine have sprouted between 3-12 days. Will the seeds get mushy and ruined if I leave them in the solution much longer? I don't want to waste these seeds, but I hate to just pot them up, because it seems unlikely that they'll grow if they haven't sprouted in the solution. Thanks for your help!!

Some may take longer than 12 days. It also depends on the ratio of peroxide:water, if it's too weak it may not work to break seed dormancy. Soaking in plain water slows them down. My suggestion would be to either remove them from the solution and put them in a container in the fridge for around four weeks to stratify and then plant them, or change the peroxide:water solution for fresh and give them a bit longer at room temperature. In my tests I left them in the peroxide with one solution change for four weeks. It's rather surprising if none of yours have germinated at all in 12 days though.

I have had people tell me some stubborn daylily seeds didn't germinate in the peroxide solution but did after subsequent stratification. If they still don't germinate on removal to room temperature after stratification then it suggests they are not viable.
