Daylilies are a hardy perennial flower with large yellow, purple, pink, or red blooms. Many daylily hybrids exist, which creates a huge array of flower shapes, colors, and sizes. A daylily flower only blooms for one day, but each plant has so many blooms they appear to be in flower for longer. Most daylilies bloom in late spring or early summer, depending on the region, and some varieties bloom twice. Germinating daylilies before planting them outdoors gives your plants a better chance of survival.
Check your daylily seeds for any moldy, mushy or hollow-feeling seeds, and dispose of these. Unhealthy seeds won’t germinate, and mold can easily spread to healthy seeds.
Mix an ounce of hydrogen peroxide with a half gallon of water. Pour the solution into small containers, one for each variety of daylily you plant to sprout. The peroxide helps daylily seeds take in moisture more effectively.
Put the seeds into the peroxide solution, and place the containers in the refrigerator. Daylilies germinate more successfully if the temperature is consistently cold.
Check the seeds every day. When you see that one or two seeds in a container have sprouted, plant all the seeds in that container. If you leave the sprouted roots soaking in the water for too long, they will get mushy and fall off. After 10 days, plant the seeds whether they have spouted or not.
Sow the germinated daylily seeds into pots filled with a very light potting mix that has been gently tamped down and moistened. The potting mix should contain more peat or sphagnum moss than soil. Plant the seeds about ½ inch deep and place the pots in a warm, sunny place.
Transplant daylily seedlings outdoors when the last danger of frost has passed, and the seedlings are well established. Put them in a place where they will get full sun, and keep them well-watered.
