Question: Pennsylvania is home to the “Mushroom Capital of the World.” Which small town holds the title?

Answer: Kennett Square, a Chester County borough of about 6,000 people, produces over 60% of the nation’s mushroom crop, with area farms harvesting more than 400 million pounds a year. The industry traces back to the 1880s, when local florist William Swayne started growing mushrooms in the wasted space beneath his greenhouse benches. It turned out mushrooms don’t need good soil or sunshine, just know-how, and generations of local farmers built on his head start. The town leans into the title: it throws an annual Mushroom Festival each September and once rang in the New Year by dropping an 800-pound mushroom instead of a ball.
