I got a pod from a friend with tons of seeds. Anybody ever start it from seeds? Looking for tips.

I've started Cardiocrinum cathayanum seed before. You probably have C. giganteum? I would expect seed sprouting to be the same. By they way @Roosterlorn, if you want to see a close lily relative with big flaps.....

When I was trying to find the Cardiocrinum germination mode, there seemed to be a lot of different opinions. I finally settled on (and it's just me talking here) that the seeds benefit from an after ripening, like most Fritillaria (another lily relative). So I would recommend in your climate, to plant them at room temperature for two weeks, then put outside in the garage (or similar temp) for 1 week, then outside in the cold for spring germination. Cardiocrinum germination is very sporadic, and you'll get more germinating from the same batch in years to come. So if anything does sprout in that first 3 weeks, you have the option of 1) growing them under lights, or 2) just ignoring the sprouts and still put outside, and new seeds (and likely more) will germinate in the spring. (Initial sprouts would probably die.)

I don't know about the species that you might have, but C. cathayanum purportedly has a very low germination rate, so I overlapped the seed by a half as they lie in the pot, covering the whole surface. Then I gently mixed them with the top quarter inch of soil, (lying flat they would impose a drainage barrier), and covered with another quarter inch of soil. In that 4x5in deep pot, that seemed to give me about 4-10 seedlings a year. Don't be too surprised if nothing comes up the first spring, but don't throw the pot out!

Even the C. cathayanum seedlings, supposedly more cold hardy than C. giganteum wouldn't make it through the winter here. I wasn't willing to bring the bulbs inside for the next 8-10 years that it would take to bloom in my climate, so I just gave the pot the same winter treatment as all my other materials. I had new sprouts for four springs, until the moss grew so thickly that I threw it out.

Yes Rick, I believe it is cardiocrinum giganteum. I saw many different suggestions on the internet as well and I figured I trust you guys more!
Well I wish I took a picture of the pod but it was about the size of a lime! I'd say it was about 3-4 times as big as a full OT or Trumpet pod. Rick is right about the "flaps". There is quite a sail to catch the wind.

These are the seeds from one pod!

This is a comparison to oriental seed chaff. (the only thing I had laying around)
I'd say an OT seed would be a little bigger than the oriental but still small in comparison.

Thanks all, I had the same question as Joe and I thought Rick had answered the question before.
