Is a sweet potato vine hard to grow?
Thanks for writing. Sweet potato vine is quite easy to grow if you have a hot, sunny spot (for the kind with edible tubers like you eat at Thanksgiving). If you're asking about the ornamental ones with gold, purple, or bronze leaves, they do all right in shade but better in sun.
Good plant combo partners include angelonia, cleome, and other tall, upright varieties. Shorter plants are often overwhelmed by vigorous sweet potato vines.
