Longwood Gardens in Kennett Square, Pennsylvania has unveiled its new $250 million ‘Longwood Reimagined’ expansion.
More than three years in the making, Longwood’s transformation of 17 acres of gardens has enhanced the central grounds with new buildings, gardens and amenities.
The largest element of the expansion is the new 32,000-square-foot West Conservatory, designed by Weiss/Manfredi with gardens and water features by Reed Hilderbrand.
Another key feature of the project is the relocation, preservation and reconstruction of the Cascade Garden, designed by Brazilian landscape architect Roberto Burle Marx and first opened in 1992.

Highlights also include the Bonsai Courtyard, a 12,500-square-foot outdoor gallery for the display of Longwood’s bonsai collection.
Paul Redman, president and CEO of Longwood Gardens said the project is “a bold leap into the future of defining what it means to be a great garden of the world whose foundation is based upon horticultural excellence”.
“This project honors our legacy by embracing innovations and sustainability practices that define 21st-century garden artistry,” he added.
“With new spaces to explore and dynamic landscapes that evolve with the seasons, Longwood Reimagined ensures that every visit will offer a fresh, immersive experience.”
‘A Longwood Christmas’
The expansion has launched in conjunction with Longwood’s holiday experience, called ‘A Longwood Christmas’. This is on view until 12 January 2025.
The event features more than half a million twinkling lights across hundreds of acres, as well as festive fountain shows, thousands of colourful poinsettias, and incredible Christmas trees.
“A Longwood Christmas is always a magical time of year, and this year promises to be even more special as we invite guests to explore new areas and 17 acres of revitalized beauty, including two new glasshouses and stunning gardens and water features,” said Redman.
One of the world’s great gardens, Longwood was founded by industrialist Pierre S. du Pont in 1906. It is home to 1,100 acres of gardens, woodlands, meadows and fountains.
