The PHS Philadelphia Flower Show is the nation's largest and longest-running horticultural event,
and features stunning displays by the world’s premier floral and landscape designers.

Started in 1829 by the Pennsylvania Horticultural Society, the Show introduces the newest plant varieties, garden and design concepts, and organic and sustainable practices. In addition to the major garden displays, the Flower Show hosts world-renowned competitions in horticulture and artistic floral arranging, gardening presentations and demonstrations, special events, a mammoth indoor Marketplace, and the Bloom Philly Festival in the weeks leading up to the Show.  

The Philadelphia Flower Show has been honored as the best event in the world by the International Festivals & Events Association, competing with events such as the Kentucky Derby Festival, Tournament of Roses Parade, Indianapolis 500 Festival, and other international celebrations.

Proceeds from the Flower Show benefit the year-round programs of PHS that have become national models of urban greening.
