World-renowned and local exhibitors bring an extraordinary range of floral, landscape, and botanical artistry to life, from immersive garden displays to iconic spaces like the Hamilton Horticourt and Design Gallery. The theme this year is Rooted: Origins of American Gardening. Gardens aren’t just made; they’re passed down through generations, carried across oceans, lifetimes, and lands. 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.
