Disney's Animal Kingdom: The Largest Garden in the World?

The Rainforest Garden: Disney's Animal Kingdom: The Largest Garden in the World?: "It wouldn't be a stretch to call this Disney theme park one of the largest botanical gardens in the world. With 500 acres composed of over 3,000 species of plants from around the world, put together with an incomprehensible budget and limitless human resources, its hard to find a more impressive public garden. Did I mention that they have the largest collection of flowering trees in North America? Mrs. Rainforest Gardener and myself don't typically visit theme parks, but for a tropical garden of this magnitude, we made an exception."
