Pennsylvania Horticultural Society announces 2026 PHS Philadelphia Flower Show theme

With a theme of "Rooted: Origins of American Gardening," the 2026 PHS Philadelphia Flower Show celebrates the stories that ground us in gardening, whether it’s the nostalgia of a grandparent’s garden, a beloved family recipe that begins with the bright scent of freshly picked herbs and vegetables, or the heritage traditions that shape how we plant, grow and gather, according to the Pennsylvania Horticultural Society.

"As Philadelphia celebrates the 250th anniversary of American independence, the 2026 Flower Show offers a chance to reflect on the gardening legacies we’ve inherited and the ones we’re growing for the future, shaped by people and plants from around the world," PHS said in a news release. "This year’s show will combine legacy and belonging with breathtaking artistry and larger-than-life creations that will take guests on a journey through a vivid world full of memory and magnificence.  

The 2026 Flower Show marks the final chapter in a three-year trilogy of themes exploring the past, present and future of gardening. In 2024, United by Flowers celebrated the current connections and community that grow through shared gardening experiences. In 2025, Gardens of Tomorrow sparked imaginations with visions of what the next generation of gardens could bring. Now, in 2026, Rooted: Origins of American Gardening looks to the past to honor the cultures, traditions and stories that have planted the seeds of today’s gardens. 

Together, these three themes tell a story of the imagination, legacy and cultural roots of gardening, setting the stage for the Pennsylvania Horticultural Society’s landmark 200th anniversary in 2027.

"This year’s Flower Show feels especially personal because every plant or garden carries a story behind it. We all have memories tied to plants, and Rooted: Origins of American Gardening is about sharing those diverse experiences and the ways they connect us," said Seth Pearsoll, Vice President and Creative Director of the PHS Philadelphia Flower Show. "It will be a show filled with memory, meaning and incredible creativity."

Now in its 197th year, the annual show is PHS’ main fundraiser.

“Rooted: Origins of American Gardening reflects PHS’ mission to use horticulture as a force for good by connecting people, places and communities through the power of plants," said PHS President Matt Rader. "As Philadelphia marks America’s 250th anniversary, this theme honors the deep roots of gardening history and culture that nourish our city and its neighborhoods. At PHS, we’re proud to carry forward this legacy by creating green spaces that foster resilience, equity and well-being for all." 

Show features will include an immersive entrance garden blending historical influences with modern design; a special four-garden exhibition celebrating the nation’s 250th anniversary, made possible by the Philadelphia Funder Collaborative for the Semiquincentennial; a houseplant and indoor plant competition with thousands of entries and open to all plant lovers; the Know to Grow speaker series, included with admission; botanical-themed crafting experiences; a marketplace of unique plants and handcrafted good; and the Kids Cocoon.
