Hi. A friend of mine has a cup and saucer vine. It looks like a cup and saucer campanula, but I can\'t find it under campanula, so it may be another kind. Do you know what the name is and where to find it?
Check out Cobaea scandens. Many seed companies stock it. https://www.gardeningknowhow.com/ornamental/vines/cup-saucer-vine/growing-cup-and-saucer-vine.htm
