Meet Our Team
Walters Gardens began as a small, family run 5-acre farm growing perennials for local suppliers. It has since grown to 1,500 acres and over 500,000 square feet of greenhouses. Still family owned, we haven’t lost sight of our (bare) roots or the values that made this company what it is. Our commitment to a high quality product and genetics have led to an expansive collection of plant introductions, lasting relationships with our customers, and a close relationship with Proven Winners® as the exclusive home of Proven Winners® Perennials.
Much of our success can be attributed to the employees who have spent countless years working for Walters Gardens and whose contributions have helped to move our company forward.
