I have a number of things on your wanted list. Check out my tradelists and let's trade. A few of the things I have that you're looking for are: Fuki (Petasites Japonicus),Sea Kale (Crambe Maritima),Good King Henry (cheopodium bonus-henricus), Groundnut (apios americana), Giant Solomon's Seal (polygonatum biflorum var. commutatum) Many items aren't on the lists; so please just ask - I probably have it! Red Willow

There is an apios that should soon be released for home gardening. It is LA85-034. I'll check my vines to see if the seeds have already shattered.

Seeds or roots. Have seeds of Paw Paw (Asimina triloba), Sassafras, Spicebush (Lindera benzoin), Devil's walkingstick (Aralia spinosa); tubers of Groundnut (Apios americana), rhizomes of Goldenseal(Hydrastis canadensis), Bloodroot (Sanguinaria); bulbs of Ramps (Allium tricoccum)

Happyday, those are indeed large tubers, but I have read that they can get much larger. This is a lightly cultivated strain, and the documentation said "basketball size" tubers were possible. I'll have to see that to believe it. As for the pods, I don't know. Mine have never pollinated, and once I managed to trigger the complex flower to pollinate itself but the pod died of heat exposure or something before it grew very much. I believe there is some sort of swamp fly that is the main pollinator but no one knows for sure. And yes, they like lots of water. I just made sure to water mine enough that the top soil looked moist whenever possible. They can't be overwatered like some garden plants, and they can also tolerate dry conditions for a bit. The conditions that I think are likely to be best are moist, sandy loam type of environments with plenty of sun. But they do seem to be tolerant of adverse conditions.
