Superbena® Cobalt™ displays vigorous dark blue-purple flowers clustered in large umbels covering deep green foliage. With a mounding-trailing habit, they function as both spillers and fillers in combination planters and are best planted at the front of landscape beds. It is heat tolerant, resists deer, and attracts butterflies.
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, switch grass 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.
