I just got back from the Flower and Garden show at Epcot. They have nationally known guest speakers each Friday and Saturday covering all topics. During the week they a have guest speakers from the University of Florida, Disney and the Sponsoring Company, which is Southern Living. When I was there Paul James from HGTV was the special guest speaker and he was great. All of the speakers cover the different parts of the US, not just Florida.
The Topairies are all over Epcot. All most everywhere you look you can find them. There is no one area that has more than the other. The center of the show is in Innovations West. They have vendors there plus demonstrations for all ages. We spent three days going to the speakers and just walking around looking. All of the plants that they use have names on them. I learned quite a lot of things to help me with my gardening. this year it runs from May 19 to June 2nd. If you ever get the chance to come it is well worth it.
Some of the must sees;
The Power of Flowers
