Two of my Calla Lillies (Zantedeschia) produced seed pods this summer. Both plants are now completely dormant but the seeds are still green and still tightly packed in the pod. I've found some information on germination but I'm wondering if these seeds are viable. One source suggests the seeds should be soaked in warm water before planting but would this be required given the seeds are not dry? Has anyone had any experience with germinating these? thanks Bruce Ottawa, Canada
