From those first seedlings planted by Pierre S. du Pont in 1907, Longwood Gardens has grown into one of the premier botanical destinations of the world, with more than a thousand acres of indoor and outdoor gardens, woodlands, meadows and majestic fountain displays. Today, Longwood boasts more than 11,000 different types of plants and trees, hosts 800 horticultural and arts events each year, and welcomes more than 1 million visitors annually.
But the du Pont commitment to natural landscapes and carefully tended gardens extends far beyond Longwood, through the grounds of Winterthur Museum, Garden and Library; the Mt. Cuba Center; the Hagley Museum and Library; and Nemours Mansion and Gardens. Individually, they're magnificent. Together, they foster a conservationist ideal that makes Wilmington and the Brandywine Valley one of the most carefully preserved regions along the east coast.
