Superbells Holy Moly Calibrachoa from Proven Winners has beautiful mottled pink and yellow flowers that bloom all season. This bestselling annual is very low maintenance and heat tolerant, it also attracts hummingbirds and does not need deadheading. Superbells, with their small, petunia-like flowers, 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.
