The Edison & Ford Winter Estates: A Rubber Experiment, a Butter-Tub Tree, and the Best 20 Acres in Fort Myers
AI-generatedWalk through the front gate on McGregor Boulevard, follow the brick path past the ticket booth, and within ninety seconds you stop walking. You have to. In front of you is a tree that does not behave like a tree. Aerial roots drop from the branches like fluted columns and sink into the ground, so what started as one trunk is now a forest of them, holding up a canopy that throws shade over the better part of an acre. People stand under it and go quiet, then start whispering, the way they would in a cathedral. It is the largest banyan in the continental United States, and it arrived in Fort Myers in a butter tub.
That tub detail is the whole place in miniature. The Edison & Ford Winter Estates look, at first glance, like a pretty riverfront garden with two old houses attached. What they actually are is the surviving evidence of one of the strangest research projects in American industrial history — Thomas Edison trying to grow rubber out of Florida weeds — wrapped inside the best inventor-buddy story you've never been told. Here's how to read it, and how to do the visit right.
The tree that was supposed to save America's rubber
The banyan was a gift. In 1925, tire magnate Harvey Firestone handed Edison a four-foot seedling — two inches across, shipped from India in a butter tub — and Edison planted it beside his lab. It wasn't landscaping. It was a job interview for a plant.
Here's the anxiety that drove it: by the 1920s, the United States made cars, tires, and machine belts by the millions, and nearly every ounce of the rubber came from British and Dutch plantations in Southeast Asia. One foreign embargo and American industry seized up. Edison, Ford, and Firestone each saw the same vulnerability, and in 1927 the three of them formed the Edison Botanic Research Corporation to fix it: find a plant that grows fast on American soil and bleeds usable rubber.
The lab went up on the property in 1928, and Edison — past 80, mostly deaf, and as stubborn as ever — went to work on it like a man half his age. He'd reportedly tell visitors he had no time to retire; there was rubber to grow. His team tested more than 17,000 plant samples, hauling in specimens from across the Southeast, drying them, grinding them, and chemically teasing out whatever latex they held. The banyan was one of those candidates; so were thousands of others — milkweed, ficus, fig.
The winner was almost a punchline: goldenrod, the roadside weed that makes Florida sneeze every fall. Edison bred a strain of Solidago leavenworthii up to 14 feet tall with enough latex in its leaves to actually matter, and he produced real rubber from it — a few experimental tires, including a set Ford reportedly ran on a car. It worked. It just didn't scale, and the gap between "works in a Fort Myers lab" and "supplies a nation's tire plants" was never going to close in one old man's remaining years.
Then it died, the way a lot of brilliant ideas die: someone built a cheaper one. Edison passed away in 1931. The project limped on until 1936, when it was handed off to the U.S. Department of Agriculture, and by then synthetic rubber was arriving from the petroleum labs and the whole premise of growing your tires evaporated. The goldenrod experiment never reached commercial scale. But the laboratory still stands, equipment and all, and in 2014 the American Chemical Society named it a National Historic Chemical Landmark — the only one in Florida. Standing in it is the best fifteen minutes on the property, because you can feel the obsession in the room.
Why Edison ended up in Fort Myers at all
Rewind forty years. In 1885, Edison — already famous, already rich off the light bulb — came down the Gulf coast on doctor's advice and bought thirteen riverfront acres in a cattle town of barely 350 people. He built a home he called Seminole Lodge and returned the next year, in 1886, with his new bride, Mina Miller Edison. For the rest of his life, when the New Jersey winters closed in, this is where he came.
He left a fingerprint on the whole town. The story Fort Myers tells on itself is that Edison imported the first royal palms and lined the road past his house with them — the reason McGregor Boulevard is still a 15-mile corridor of grey-trunked palms today, and the reason Fort Myers calls itself the "City of Palms." Drive McGregor slowly on your way in; it's part of the exhibit.
The friendship next door
The second house on the property belonged to Edison's best friend, and the story of how it got there is genuinely sweet.
Henry Ford met his hero in 1896, when he was an unknown engineer at an Edison electric company and Edison, at a convention dinner, told the young man his gasoline-engine idea was worth chasing. Ford never forgot it. Years later, when fire tore through Edison's West Orange plant, Ford reportedly loaned him a fortune to rebuild, no real strings attached. And in 1915, Ford did the thing a true superfan does: he bought the house right next door in Fort Myers — a craftsman bungalow he named The Mangoes — so he could spend winters beside the old man.
What they did down here is the best part. With Firestone and the naturalist John Burroughs, they called themselves the "Vagabonds" and went camping in the Everglades and along the Caloosahatchee in a caravan of cars. They boated out to Sanibel, Captiva, and Pine Island. They square-danced on the dock to phonograph records. And when Edison's health failed and he was confined to a wheelchair, Ford — this is real — bought himself a wheelchair too, so he could race his friend across the lawn. Ford made a point of being in Fort Myers every February 11 to celebrate Edison's birthday. You don't get a story like that at most botanical gardens.
What's actually on the 20 acres
Plan your loop around four things, and don't rush any of them.
The homes. Seminole Lodge and The Mangoes sit side by side, both elevated on piers — which is exactly why they shrugged off Hurricane Ian. You view them through open doorways and porches; the interiors are staged with family furniture, much of it original.
The pool. Edison built a 50-by-20-foot swimming pool in 1910, believed to be poured from his own Edison Portland Cement, and it's often cited as one of the first modern residential pools in Florida. It held water for decades without a major leak, which Edison took as a personal advertisement for his concrete.
The gardens. The grounds hold more than 1,700 plants spanning hundreds of species from around the world — many of them descendants of Edison's own experimental plantings, alongside the family's fruit trees and a giant Mysore fig that's nearly as imposing as the banyan. This is a working botanical collection, not just landscaping, and the on-site nursery still propagates and sells cuttings from it.
The Moonlight Garden. Mina's pride. She hired the celebrated landscape architect Ellen Biddle Shipman to design it in 1929 — a formal garden of night-blooming, fragrant flowers framing a reflecting pool, meant to be walked at dusk. It's the prettiest corner on the site and the one most people speed past. Don't.
The museum and lab. The 15,000-square-foot museum holds Edison's inventions, a rotating "Edison & Rubber" exhibit, and a row of antique cars — including a Model T that Ford gave Edison, because of course he did. Then the laboratory, described above. Give the museum 45 minutes minimum.
Doing the visit right in 2026
Buy your ticket online at edisonford.org — it's a couple of dollars cheaper and you skip the booth. The site is open 9 a.m. to 5:30 p.m. daily except Thanksgiving and Christmas, at 2350 McGregor Blvd.
| Ticket (self-guided) | Price |
|---|---|
| Adult | $25 |
| Teen (13–19) | $20 |
| Child (6–12) | $15 |
| Child 5 & under | Free |
| Adult guided tour | $30 |
My honest take: skip the upcharge to the guided tour unless you love a docent. The self-guided ticket comes with everything, and the signage plus a free audio option tells the story well. Spend the $5 difference on a cold drink at the café instead — you'll want it. Go at opening. By noon the unshaded stretches of garden are baking, and the banyan is a lot more magical when you're not sharing it with three tour buses.
Budget two and a half to three hours. Every section runs longer than you'd guess.
Make a day of it
The estates anchor a genuinely good Fort Myers day, and the rest is mostly free.
If you're here between December and February, drive ten minutes to Manatee Park, on the warm-water discharge canal of the FPL power plant. When the Gulf turns cold, manatees pile into the warm outflow by the dozens — it's the closest thing Southwest Florida has to the famous springs up north, and you can watch them from a boardwalk for the price of parking. (If you'd rather get in the water with them, that's a different town — see our guide to swimming with manatees in Crystal River.)
Then point the car downtown to the River District, Fort Myers' walkable historic core — brick streets, the 1933 Sidney & Berne Davis Arts Center built from Florida Keys limestone, riverfront restaurants, and a monthly art walk. It's where locals actually spend the evening.
And if your trip has more than a day in it, Fort Myers is the mainland gateway to the islands Edison and Ford used to boat out to. Cross the causeway to hunt shells on Sanibel, or head south to where the coast frays into mangroves on a Ten Thousand Islands run out of Naples. Want a pure beach day instead? The squeaky quartz sand of Siesta Key up in Sarasota is a 90-minute drive north.
But start under the banyan. It's the rare Florida attraction that's exactly as good as people say, and the longer you know the story behind it — a butter-tub seedling planted to win a war over rubber — the better it gets.
