We choose to feature Proven Winner plants because Proven Winners searches the world to bring you
vibrant flowering annuals, perennials and shrubs that deliver the most beautiful gardens. Each Proven Winner variety has been trialed in numerous sites and situations and have been found to be easy to grow and care for. These fabulous plants feature bright colorful blooms and are healthy and vigorous. Proven Winner rooted cuttings and bare root starts are only grown by a few greenhouses in Michigan. These select few
greenhouses are thoroughly screened for viruses and diseases ensuring that only healthy plants are sent out to small growers such as Hook’s for resale. Hook’s Greenhouse is a Proven Winner certified garden center. Our friendly and knowledgeable employees undergo Proven Winner training and testing each year as a part of this certification.
