Designers at the Flower Show

Exhibitors are drawn from all over the globe for this annual tribute to horticulture – international, national, and local designers show off their expertise as they compete for Best in Show in landscape and floral categories.

The PHS Philadelphia Flower Show has been held in the Pennsylvania Convention Center since 1996. The 2021 Show will be held in an outdoor location for the first time in its history to be the safest event possible for our audience.

 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. It annually attracts an audience of 250,000 at the Pennsylvania Convention Center, with visitors coming from all over the world. Typically held in the cold, gray month of March, the blooming trees, shrubs, and flowers bring the beauty, fragrance, and colors of Spring to a winter-weary audience.

The Pennsylvania Horticultural Society has been running the Flower Show for over 100 years. The Philadelphia Flower Show acts as the largest fundraiser for PHS, helping to fund its year round community programs.

Our team begins planning for the next show about 18 months in advance. Typically exhibitors are chosen and invited to the show about 10 months ahead of the show.

Yes. We have had a variety of themes from year to year, for example the theme for the 2020 Show was Riveria Holiday.

Yes. We want the show to have an overarching theme for the guest, so each designer is asked to interpret the theme as their design challenge.

The official number varies from show to show, but across all the categories of exhibitor we have about fifty.

We source our designers from all over the world, some from right here in Philly while others have come all the way from Australia.

With this kind of designer, PHS pairs them up with a local contractor that will manage the build, help with local plant sourcing, and maintenance of the exhibit throughout the nine days.

Our designers work tirelessly with local growers such as PHS's own Meadowbrook Farm to force their plants into optimal condition in time for the show, or they will have the plants delivered from warmer climates such as Florida or California.

Our gardens vary in size depending on the floor plan, but typically they span from 1000 to 1500 square feet.

One of the most challenging but exciting aspects of our show is the short build time. Our designers are given only five days to build their exhibits from the ground up to be show ready. This fast paced environment continues during breakdown where designers are only given 3 days to completely remove their exhibit from the show floor.

Many of the plants are given a second life either in other landscapes or at one of the PHS Pop Up Gardens, that you can visit throughout the summer and fall. PHS's goal is that all other plant material that is spent at the Show's end is composted.
