Superbells Lemon Slice Calibrachoa from Proven Winners has blossoms with a unique pinwheel pattern of yellow and white. The small, petunia-like flowers bloom all season on cascading foliage. It also attracts hummingbirds and does not need deadheading. This bestselling, award-winning annual is very low maintenance and heat tolerant. Superbells are perfect for containers because they need soil with good drainage. 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.
