Most Daylily seeds need cold stratification so that's where you need to start (unless the instructions say something about pre-stratified). Mix the seeds with damp sand or place them on damp paper towels, spray them with a fungicide and put them in a plastic bag. Stick the bag in your refrigerator for 1 to 2 months. Check them periodically to make sure they aren't starting to dry out, mold or germinate. If they germinate, plant them. If they mold, spray with more fungicide.
When you plant them, bury the seeds about 1/2 inch deep and keep them damp. They should start to germinate in 1 to 2 weeks. If your refrigerator has lots of space, you can plant the seeds in 4 inch pots, cover with plastic wrap and refrigerate them.
"will not come true from seed" means the plants you grow may not look like Triple Trinity Daylilies. Seeds contain the DNA from all the ancestors that went into making the Triple Trinity Daylily. Therefore, a plant grown from seed can exhibit any of those characteristics or combination of those characteristics. Its the reason you and your siblings are not carbon copies of your parents or each other, although you probably resemble them.
