For our 15th anniversary, 40 just wasn’t enough.

This year’s class is so strong, we’re celebrating 41 outstanding honorees, a fitting way to mark this milestone.

The horticulture industry is driven forward by passionate professionals who bring fresh ideas, strong leadership and a commitment to progress. Each year, a new class of emerging leaders demonstrates how innovation, collaboration and dedication continue to shape the future of the horticulture industry.

The celebration this year at Cultivate’26 was one for the books! So many of you showed up to clap and shout for our honorees this year, and as you can see in the photos below, we quickly ran out of chairs to seat the hundreds of people that attended. Thank you all for coming and showing of 2026 honorees how important they are to our industry.

It’s time to introduce GPN’s Forty Under 40 Class of 2026. These honorees represent the next generation of horticulture, making meaningful contributions across all areas of the industry and helping it grow stronger, more resilient and more dynamic.
