Longwood Reimagined

Longwood Reimagined A New Garden Experience

For more than 115 years, we have harmoniously blended art and science to create a horticulture experience of unparalleled splendor. With the realization of Longwood Reimagined: A New Garden Experience—a sweeping reimagination of 17 acres of our Conservatory and grounds, opening November 22, 2024—we are honored to enhance, steward, and preserve one of the world’s most important, most beautiful collections of gardens and glasshouses.

Stunning new buildings, wondrous new indoor and outdoor gardens, surprising new guest experiences, and much more await. We’re expanding our grounds, connecting them from east to west in a beautiful, unified journey of lush, formal gardens to open meadows to winding paths to breathtaking Brandywine Valley vistas. We’re preserving and enhancing our cherished spaces to better showcase and grow our outstanding collections. We’re reflecting our founder’s vision and embodying our mission to create a world apart accessible to all for the celebration and enjoyment of horticulture. We’re entering our next chapter ... with you.

Longwood remains open throughout the project and continues to be a world apart filled with memorable moments and beautiful experiences.

Beauty in the Making

As Longwood Reimagined: A New Garden Experience continues to take shape and as our cultural landscape evolves, we are delighted to share with you a few of the many facets of this incredibly detailed project … so you can see true beauty in the making.

West Conservatory

Built on the great 19th century tradition of glasshouses and enhanced with new, sustainable technologies, our new 32,000-square-foot West Conservatory is the centerpiece and largest component of the project. Like many of Longwood’s renowned features, it has a close relationship with water and seamlessly integrates the old with the new. Its asymmetrical peaks will rise from a pool on which the entire building will seemingly float, while its islands of interior Mediterranean-inspired gardens will be set amid pools, canals, and fountains in an exquisite tapestry-like design.

Cascade Garden

We’re making history by relocating, reconstructing, and preserving our prized Cascade Garden—the only design in North America by acclaimed Brazilian landscape architect Roberto Burle Marx. A historic garden has never been moved as a whole and preserved in this way, and we are honored to work with a team of scholars, landscape architects, preservation experts, and the Burle Marx Landscape Design Studio while doing so. This 3,800-square-foot custom-built, stand-alone jewel box will allow the plants more room to continue to grow and flourish.

Bonsai Courtyard

We’re establishing a new outdoor Bonsai Courtyard for what will soon become one of North America’s most outstanding bonsai collections. Located beside the West Conservatory, this outdoor gallery space will artfully showcase our small yet mighty specimens—many of which are more than a century old—allowing many more to be on display at one time, fulfilling our guests’ enduring fascination for these gorgeously graceful plants.

We are proud to announce that we are receiving a gift of 50 bonsai from The Kennett Collection—the finest and largest private collection of bonsai outside of Asia.

Waterlily Court

Designed by renowned landscape architect Sir Peter Shepheard in 1989, our beloved Waterlily Court will be renewed and enhanced. Framed by our new Bonsai Courtyard, this refreshed aquatic garden will be redefined as an outdoor room and further strengthened as a central destination, while serving as a gateway to the new West Conservatory and relocated Cascade Garden.

New Landscapes

The creation of new, imaginative outdoor pathways and vistas will not only expand and connect our Conservatory grounds from east to west, but also celebrate the beauty of the Brandywine Valley along the way. Think open meadows, a sweeping terrace leading toward a stand of hundred-year-old sycamores we have purposefully saved and worked into the landscape, a shaded promenade, and infinite viewpoints from which guests may take in the spectacular seasonal vistas for which our region is so deservedly known.

Restaurant & Event Spaces

Carved into the topography facing the Main Fountain Garden, a new public restaurant and private event space will overlook the spectacular fountain displays beyond. From its series of trellis-like ceiling vaults and architectural elements that echo the forms of the Main Fountain Garden, right down to its bespoke furniture crafted with reclaimed wood from Longwood trees, every detail of this remarkable space will delight, entertain, and inspire.

The Grove

A refurbished and expanded building with new state-of-the-art studios, virtual learning studios, a library, and staff offices, The Grove will become a central hub for our community of staff, students, and volunteers ... as well as a place of learning, growth, and discovery for all. Above all else, The Grove expands our reach in delivering our mission and serving our greater community.

Orchid House

As part of the initial phase of transforming the area, our beloved century-old Orchid House will be preserved and expanded to a gallery-like space in which guests will find themselves surrounded by hundreds of orchids. The restoration project will result in a new glass roof, new and restored display cases, restored bronze windows, custom frame trellises, and more … all resulting in more immersive display opportunities.
