Sure, the Epcot International Flower and Garden Festival has been giving guest floral and topiary displays for over 20 years now, but what if it was something you could experience daily at the park?
As part of the ongoing expansion project for Epcot, an idea being kicked around is the “Gardens of Wonder”, which would be a series of displays at each pavilion that would capture the essence of that pavilion (Future World and World Showcase alike) and feature a Disney character or characters connected to the theme. These floral and topiary displays would welcome guests to each experience.
For example, Wall-E and Eve in topiary form would welcome guests to Mission: Space, while Anna and Elsa would do so in Norway. The idea is that every pavilion in World Showcase and Future World would receive one of these small gardens. It does make some sense based on the amount of green we see in concept art for the further development of Future World, so natural displays like these will be a big part of the park going forward. However, it would be intriguing to see how these would be maintained all year long, as opposed to just during a 3-month festival.

This idea has not been approved as of yet, and some recent shakeups in the new creative direction of Epcot may lead to this idea getting scrapped, but only time will tell.
Love the idea.
Hope it survives.
