Prime Rosemary from Proven Selections is a kitchen staple in Mediterranean and Greek foods, used to flavor soups, sauces, breads and meats. It is a salt-tolerant perennial that is soft, lush and can grow up to 3 ft. tall. Grow in gardens, raised beds and containers and use fresh or dried. 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.
