For Longwood Gardens Inc.

Heritage Landscapes created the Longwood Landscape Evolution to synthesize into an accessible form an understanding of Pierre S. du Pont’s design intent for these renowned gardens and the evolution of this nationally significant public horticulture venue. Based on this historical framework, we collaborated with Lord Cultural Resources to provide the landscape components of the Longwood Gardens Heritage Management Plan. Our work included:

  • Study and synthesize over 4,000 primary and secondary source documents
  • Narrate an illustrated landscape origins and evolution
  • Create organizational framework for future scholarly reference
  • Aid in developing a comprehensive approach to managing heritage assets
  • Identify future documentation, curation and preservation directions

Longwood Landscape Evolution, organized by seven eras and fifteen areas, provides an in-depth evolutionary understanding of this significant landscape. Building on that foundational knowledge, the Longwood Gardens Heritage Management Plan and the Longwood Interpretive Plan, to serve as foundational documentation that informs future landscape decision making for Longwood Gardens leadership and consultants.
