This looks like another sweet potato plant to me . I got a cutting from a friend but she wasn't home when I actually went back with clippers to get the cuttings of a sweet potato vine she is growing Beautifully!!
This plant was next to it. Seems to be growing exactly the same, looks very similar but obviously leaves are different colors.
so I'm unsure what this purple and green plant is.
The one I originally went to get was a light green plant, I recently learned is a sweet potato plant . Iv never grown them so I dont know what other types there are of sweet potato plant.
