Tricolor Sweet Potato Vine from Proven Winners has beautiful green, pink, and white leaves that will trail up to 6 ft. over hanging baskets and containers. This award-winning ipomoea is easy to maintain and excels in hanging baskets, flower beds, borders, and window boxes. They love heat and humidity. We exclusively grow our annual grandes in Eco+Grandes for a greener tomorrow! Plant Powered Packaging by Proven Winners: Introducing the full annual Eco+Grande collection. The Eco+Grande is a game-changing Plant Container made from plants. This compostable container is made from starchy renewable plants like corn, switchgrass and sugar beets grown in the United States. The Eco+Grande has nutrients built into the wall of the container that helps plants grow bigger and faster all season if planted in the ground. When the Proven Winners Eco+Grande container is discarded in the garbage can, it will naturally break down faster in a landfill than a traditional petroleum-made container. The container will get smaller and smaller until microbes consume it, turning it back into an inert organic product.
