My 'Golden Chalice' vine has produced 5 huge seed pods. One is now turning white, the rest are still green. I think it turns brown after white. It has been a while since it set seed. But how do I know when the pod is ripe? Do the seeds come out all fluffy and fly away? Are they big seeds and just fall to the ground? I have no idea when to pick the pod, I don't want to loose the seeds.

Does anyone know about this vines seed pods, and when I should pick them to get seeds. I assume they will grow from the seeds. Are they hard to germinate?
