Thank you for your reply about the runner x common beans. It was very nice of you to consider me.
I know you have been doing work with sweet potatoes, but have you done any work with the different leaf colors? This website shows all sorts of different sweet potato leaf colors including some variegated types. I personally am very interested in the potential leaf colors that might be discovered. Leaf shape is also quite interesting.
I suppose @Ascentropic might know the answer to my grafting problem. He knows a lot about grafting. His Substack is what inspired me to try grafting in the first place.
