Oscars 2016: All the Details of the Governors Ball

Wolfgang Puck dishes about the Governor's Ball menu and more.

— -- After all the Oscars are handed out at tonight's show, the celebrities will make their way to the official after-party: the Governors Ball.

The bash, which will be attended by some 1,500 people, has been in the works for more than six months, according to event producer Cheryl Cecchetto, the founder of Sequoia Productions.

"I thought to myself, 'We need to make sure we have a contrast of the black-and-white to a palette that will make them pop," Cecchetto told ABC News, adding that she decided on a pink palette. "When you walk in, all you see is the celebration of film."

However, the bright walls created a bit of a conundrum for Mark Held, of the florist Mark's Garden. To create a contrast, he and his team decided to use more than 10,000 white flowers, including calla lilies, gardenias, ranunculus, phalaenopsis orchids, roses and succulents, and pair them only with greenery.

"All the flowers we've chosen are important flowers that do stand on their own. They're sculptural and they have a relationship with Hollywood's history," he explained. "You see gardenias in someone's hair. The calla lilies you see Hepburn."

Said the brand's global executive director, Benoit Collard, "This is a very special tribute from the house of Piper-Heidsieck to the great job they're doing."
