A city staple since 1829, the annual Pennsylvania Horticultural Society (PHS) Philadelphia Flower Show — the oldest and largest indoor horticultural event in the world — draws tens of thousands to the Pennsylvania Convention Center each year. The floral spectacle, returning in 2026 for its 197th year, brings together hundreds of florists, landscapers and designers for one of the city’s most anticipated yearly events.

Beyond the displays, the show hosts major juried competitions, tons of gardening talks, demonstrations, special events, celebrities, a sprawling market, live performances and plentiful food and drink options. Stay tuned for the 2026 show’s theme.
