Daylilies grow easily from seed with no preteatment. Your plants may not resemble the parent, but thats OK, there is about 50,000 varieties now, and so whats one more. You can grow a peach from a pit, but it will take 10 years to find out it is not a good peach, so I would not. Al

You can grow a peach/nectarine from a pit, it will take only 3 years to find out it is a good or a worthless fruit.
Growing on their own roots Prunus varieties develop very quickly in fruit stage.

Even, a Peach/Nectarine cutting (taken from a perennial tree) can bear some fruits in a second year.
So, give it a try it's worth.
