"We are proud to recognize this year's award winners whose exceptional design, horticultural skill, and storytelling elevate the Flower Show experience. Their work not only honors the rich roots of American gardening but also demonstrates how creativity and innovation can inspire more resilient, beautiful, and connected communities," said Seth Pearsoll, Vice President and Creative Director of the Flower Show at PHS.
