David, This is very interesting. I'm curious about sources of tuberous Pelargonium varieties -- seeds or tubers? If it is so tricky to get them past the one-year mark, I'd rather buy a few established plants, either as dormant tubers or as plants. Are there any the grow primarily in summer, so that we could grow them outdoors in summer here in Indiana? We have limited space in the greenhouse for winter growing plants, but it is easy to store summer growing tender plants that are dormant in winter. We just set the pots in a corner of the basement. I've been intrigued by the varieties of Pelargonium that I have seen on my two visits to South Africa. Of course, I haven't noticed whether any that I've seen were tuberous or not.
