I suspect your problem is leaving the seeds in the Hydrogen Peroxide. Soaking hard shelled seeds in Hydrogen Peroxide is a method of chemically scarifying to help break dormancy. But, Hydrogen Peroxide is chemically unstable so when the H2O2 molecule comes apart (when added to water), it rips holes in cell walls. I doubt those seeds will germinate but, you may as well plant them and prove me wrong.
Mixing seeds with damp sand and putting them in the refrigerator for a couple months will break dormancy and is a lot safer. When I have felt the need to scarify, I rub the seed gently on an emory board a couple times. Or, if you have a lot of seeds, sandwich them between layers of fine sandpaper and rub back and forth a couple times. The purpose is to allow water into the seed without breaking the seed coating.
But I don't think Daylily seeds need to be scarified, only stratified.
