Largest banyan tree in the continental United States

I’m touring the Edison-Ford Winter Estates in Fort Myers, FL today. I bought a Groupon a few months back, which I’d clean forgot about. I decided to use it today, before it expires.

This is the place where Edison continued his research during the winter months. He was looking for a cheap, locally-produced source for making rubber. The estates are therefore populated with all sorts of exotic botanical candidates for rubber production. the sub-tropical climate of Southwest Florida proved ideal for growing many of the plants Edison needed to study.
