Even if they are NOIDS, you can usually tell what division and type they are by foliage and flower character and color, blooming time frame and so on. Try to cross pollenate within the same Division for starters. And keep the seed pod on the plant until it has fully ripened and begins to split open at the end. Shell out and dry seeds for away from sunlight a few days, then freeze until ready to plant. I usually plant in late January but most lily seeds can be planted any time in the early Spring. Planting seeds in baggies or pots inside and grown under lights for 3 months before moving outdoors is almost always much more successful than sowing directly in the ground.
