Mojave Yellow Portulaca from Proven Winners has vivid yellow flowers all season and succulent-like foliage. It is heat, drought, and salt-tolerant, attracts pollinators, and does not require deadheading. Use in pots, window boxes, baskets, and as a ground cover. The flowers of Portulaca will close at night and reopen the next day. These are tough plants that will tolerate poor soils and regular moisture and do not need a lot of fertilizer to perform well. Fertilize monthly with Proven Winners Water Soluble Plant Food. 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.
