Rarely seen prints from Andy Warhol's "Flowers" series, from the Bank of America Collection, will also be displayed.
Billed as the world's largest indoor flower show, the Philadelphia Flower Show dates back to 1829. It also includes plant judging, a butterfly garden, interactive exhibits and craft workshops.
Attendance will be carefully watched after last year's ticket sales fell 17 percent from 2012. Organizers said many groups canceled due to overhyped weather forecasts for snow, which never materialized. About 270,000 visitors came to the show in 2012.
Becher said Thursday that ticket sales were trending 30 percent ahead of last year.
