Violet Knight Lobularia from Proven Winners displays stunning purple blooms with a yellow eye. It is heat tolerant, has a fragrant flower, and attracts bees and butterflies, all while producing magnificent blooms all season long. Fertilize weekly with Proven Winners Water Soluble Plant Food. If hardened off, they can be planted in early Spring when temperatures still fluctuate wildly, but these improved varieties also have much better heat performance. They aren't bulletproof plants yet, but they do bloom prolifically through the Summer in most areas. Then as things cool off again in Fall the plants adapt once again to wide variations in temperatures. They will bloom prolifically in Fall until a good hard frost finally causes them to call it done for the year. 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.
