Half the country's white button mushrooms come from a five-mile radius around this borough. Longwood Gardens is up the road. Unionville-Chadds Ford schools are top-five in PA. The Brandywine Valley starts here. None of that has anything to do with the State Street walkable downtown that holds it all together.
Kennett Township was settled by Welsh and English Quakers in the 1690s. Two centuries of farming. Then in 1885 a florist named William Swayne — frustrated by the heat ruining his carnations in summer — discovered that his greenhouse beds were ideal for growing the white button mushroom that had just been imported from France. The American mushroom industry was born here.
By 1925 there were over 200 mushroom growers in the Kennett Square area. By 1965 there were over 600. The combination of dense Italian-immigrant labor (which made the labor-intensive growing process economical) and a unique microclimate of cool, humid Brandywine Valley soil made Kennett the indisputable American capital of the industry. Today the region produces about half of all U.S. mushrooms — over 500 million pounds a year.
The borough itself stayed small. Three thousand residents in 1900. Six thousand by 1970. Around eight thousand today. The downtown is a few blocks of State Street with restaurants, the Kennett Symphony, the Mushroom Cap shop, the Genesis pharmaceuticals headquarters, and a handful of historic buildings. The mushroom industry mostly happens in the surrounding township — long, white, single-story growing houses arranged in rows on what used to be Quaker farms.
Five minutes east on Route 1 is Longwood Gardens — 1,100 acres of horticultural display, 10,000-pipe organ, fountain shows on summer Saturday nights. Pierre du Pont bought the property in 1906 and built it into one of the great American gardens. Today the foundation runs it as a public destination that draws over 1.5 million visitors a year. Longwood's presence has shaped Kennett's housing market more than the mushroom industry has — wealthy weekend-house buyers from Philadelphia and Wilmington discovered the area through Longwood and started restoring Brandywine Valley farms in the 1950s and 60s.
The Unionville-Chadds Ford School District — covering Kennett Township, Pennsbury Township, East Marlborough, Birmingham, and parts of Pocopson — has been ranked top-five in PA for fifteen years running. Smaller and quieter than the T/E corridor north of here, it draws the same kind of buyer for the same reason: school-driven family pricing on a longer horizon.
Three blocks of restaurants, the Mushroom Cap, the Kennett Brewing Company, La Verona, the State Street Diner. Walkable, friendly, the kind of small-town downtown that's been losing ground everywhere except here.
Annual September festival. Closes State Street. Tens of thousands attend. Mushroom-themed everything. The borough's biggest civic event, running since 1985.
Annual passes are common. Locals walk it like a city park. The fountain shows in summer are a recurring weekend ritual. The Conservatory at Christmas is a tradition for every Brandywine Valley family.
UCF is the academic anchor. Top-five in PA. Smaller than T/E or Lower Merion but matches them on outcomes. Why most family buyers come.
Drive five minutes south or west and you're in horse country. Working farms, equestrian estates, du Pont-era estates. The countryside hasn't been suburbanized the way Tredyffrin or Lower Merion has.
Most Kennett residents commute to Wilmington (DuPont, Chase, AstraZeneca) rather than Philadelphia. 25 minutes to downtown Wilmington. Sometimes the better job market is across the state line.

Kennett moves quieter than the T/E corridor — but the UCF catchment singles still go fast. Brandywine Valley estates often trade off-market entirely.
