I've been doing some grafting work in Ipomoea species, and all of the papers I've referenced recommend a variety of I. nil 'Kidachi' (or sometimes 'Kidachi-Asagao', but asagao just means morning glory in Japanese). This seems to be a dwarfed japanese morning glory which produces thicker, shorter stems, which makes it ideal as a rootstock, while retaining the floriferous nature of many I. nil varieties.
However, I can't find this variety anywhere. Has anyone heard of this, or know where I might look for it?
Thanks.
