Dear All, Nice to hear that the seeds I donated found a good new home! I have never considered this Ipomoea could be cold hardy, mine is pot grown and kept dry but frost free in the cellar in winter. It is a very good pot plant indeed. This year it has sprouted very late and has not flowered yet but is growing fine. It might be an idea to sow some of the seed and try it for hardiness with a good mulc and rain protection. Are there other Ipomoeas that could be grown this way? Bye for today, Uli
