Hi Ken, I. leptophylla also grows in the dry high desert of northern New Mexico. It's a beauty but difficult to germinate. I know of a population that is hardy to at least zone 5. Haven't been out there this year so don't know if there's seed. Anyone wanna pay for my gas to go look? ;-) On the other hand, Agua Fria Nursery here in Santa Fe had some seedlings out on the tables early this year. They don't usually do mail order, but you might call, ask for Mark Pennington (the son) and plead. If you cover plant and shipping costs, I'll check stock and send you whatever they have left. - Barbara Ken wrote: > Another hardy Ipomoea is I. leptophylla, written about by >Claude Barr in Jewels of the Plains.
