I don’t think I’ve ever seen a Japanese morning glory (Ipomoea nil) I didn’t like, but this one—‘Keiryu’, also known as ‘Mountain Stream’—really takes things to the next level, with tie-dye-patterned, blue-and-white flowers and chartreuse-y green foliage marked with silver gray. The vines get 8 to 10 feet long here. They’re rather slow to get started but more vigorous once they start climbing. I just wish they would set more seed! Full sun. Annual.
Harvested in September and October 2020. At least 8 seeds. Be aware that these seeds are open-pollinated, and I do grow other morning glories, so there is a possibility of some genetic variation. I do try to keep the various strains well separated, though, to minimize the chance of crossing.
