Heritage and History
Proven Winners was founded in 1992 as a collaborative marketing program between a small group of plant breeders and growers who wanted to bring trialed, tested, and proven varieties directly to the retail market. The concept was simple: sell only plants that had been rigorously evaluated in growing trials across multiple climates, ensuring customers received varieties that actually performed in their gardens.
The brand quickly grew into one of the most recognized names in ornamental horticulture, known for vibrant color, strong plant habit, and reliable performance.
Grown in the USA
Proven Winners plants are propagated and grown by a licensed network of growers throughout the United States and Canada. The trialing program tests new varieties in diverse climates before any plant reaches retail, and each variety bears a color-coded tag indicating ideal sun exposure and care requirements.
The company's Sycamore, Illinois headquarters coordinates the research, marketing, and licensing that keeps Proven Winners plants among the top-selling ornamentals at garden centers nationwide.
