PHILADELPHIA (CBS) — The Philadelphia Flower Show is reportedly ahead of schedule in getting set up for its scheduled opening on Sunday.

The theme of this year’s show is “Hawaii: Islands of Aloha” (see related story).

Alan Jaffe, spokesman for the Pennsylvania Horticultural Society, which sponsors the show, says the groundwork (no pun intended) is already in place.

“We’ve got a lot of 20-to-25-foot palm trees on the show floor at this point,” he tells KYW Newsradio. “I see the beginnings of a waterfall building up toward the ceiling of the Convention Center.”

And he says the colors of Hawaii are already evident.

“A surprising amount of plants (are delivered), because usually the real color doesn’t appear until Thursday or Friday of setup week. And it looks like they’re already getting some of the tropical trees in here,” he said.

Jaffe says that, new this year, part of each ticket sale will go toward City Harvest, which helps feed people who don’t have access to fresh vegetables through the growing season.
