Sounds like ground planting is probably just as easy. I used to just let the pods mature on plant until mostly dry, pick them and dry in the shed. Take the seeds and plant with some kind of moisture holding whatever - if I had leftover compost, I'd use that, or just good soil - under some other foiliage for protection. Keep it watered.

I guess mine didn't need to be frozen first. I have 9 or 10 daylilies and started out with 3.

That was one of the fun things about this plant. I was surprised it took me so long to *discover* it, once I figured out how easy it was to propagate. Great fun to garden with kids with this one. Always a flower to let them pick, seeds easy for little hands to manage, and this year we can divide and replant together.
