Susan, if you want to see what you get from the seed pods, leave them on until they dry up, watch closely and get them just as they begin to split or look like they will tomorrow. The plants that you get will of course not be like the parent plant but a hybrid of whatever the bees pollinated for you, maybe good maybe not. To keep the same plants, which you hopefully have named and know what they are, you must use the rhizome or clone of the plant to plant more of the same. You can, of course, save the seed and also divide up the rhizomes thereby getting more of the same plant and planting the seed to see what you do get in about 3 years.
