Yes, sweet pea vine can be an invasive plant in certain areas. It is native to the Mediterranean region and has been introduced to many parts of the world as an ornamental plant. In some areas, it has become naturalized and can spread aggressively, outcompeting native plants and forming dense stands that can block out sunlight and prevent other plants from growing. Sweet pea vine can also climb up trees and other structures, causing damage and potentially posing a safety hazard.
