I'm assuming this means this Ipomoea is hardy to zone 7 or
thereabouts? Or does it self sow?
Another hardy Ipomoea is I. leptophylla, written about by
Claude Barr in Jewels of the Plains. I finally bought seeds
this spring, but so far they aren't growing very much. There are a couple
small seedlings in gallon cans, which might be part of the problem--my
understanding is that this plant likes to establish a large and deep storage
root (tuber?) before it makes much top growth.
This is a genus I know little about, so if there are other "hardy"
Ipomoea I'd be interested in hearing of them
