A Brief History of Proven Winners®

Proven Winners® was founded in 1992 by Proven Winners Carleton (formerly Four Star Greenhouse, owned by the Smith family) and Proven Winners Loudon (formerly Pleasant View Gardens, owned by the Huntington family). The goal then was the same as it remains today: to introduce the best, most unique, high performing plants, produce them under strict quality standards, and implement innovative marketing strategies to promote them to the world.

 Tom Smith of Proven Winners Carleton first began growing plants in 1977, focusing mostly on finished crops of bedding plants grown from seed and sold at local markets. The Huntington family began Proven Winners Loudon in 1976, growing plants for local florists.

 Together in 1992, they founded the Proven Winners brand on the premise that unique annuals could be bred for garden performance and produced vegetatively to ensure uniformity for growers around the world. Over 30 years later, Proven Winners has become The #1 Plant Brand® and The Brand Gardeners Trust®.

Proven Winners Today

Proven Winners ushered in a new era of growth in October 2025, beginning the next chapter under a new ownership structure for the brand. By combining forces under one company — Proven Winners® — the Smith and Huntington families now work in partnership with Staple Street Capital to deliver greater simplicity, scale and service for growers, retailers and consumers.

By pooling resources, our brand has the ability to develop additional national programs, enhanced ordering and distribution tools, and stronger marketing to drive consumer demand. A key focus is expanding reach into underserved markets, making it easier for everyone to access the brand.

Our mission remains the same as always: to make gardening easy, successful and inspiring for everyone through the introduction of plants that deliver superior garden performance. While we remain rooted in our founding culture, we’re just getting started. We are excited for what the future will bring and appreciate your trust in Proven Winners.
