These vines will tangle themselves around the nearest support and are perfect for hanging containers and flow just as easily over walls and raised garden beds. Black-eyed Susan vines bloom repeatedly from May through fall. You will get the most flowers and the healthiest plants if you grow your black-eyed Susan vines in full sun (at least six hours of direct sunlight on most days). Keep the soil moderately moist. Mulching around the base of the plants will help to keep the roots cool and moist.
