Superbells Blackcurrant Punch Calibrachoa from Proven Winners displays a deep black eye and bright pink-purple edges. Abundant, small petunia-like flowers bloom from planting until the first frost, attract hummingbirds, and do not require deadheading. Calibrachoa do not like to have constantly damp soil, they will do well in the ground only with good drainage. For most gardeners, containers are the best use. For best performance fertilize with water-soluble fertilizer weekly and give a light trim once or twice a season. 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.
