The beauty of conservation – developing a science-based conservation horticulture programme at Longwood Gardens, Pennsylvania, USA

Abstract

While historically serving ornamental, medicinal and agricultural purposes, botanic gardens and arboreta have opened their doors to the public and have extended their missions to encompass the study, preservation and support of plant diversity. Longwood Gardens (Kennett Square, PA, USA) has embarked on this journey, leveraging its scientific expertise to establish a conservation focus. Navigating this initiative with its strength in horticulture, the Longwood team outlines key steps in creating a conservation horticulture programme, emphasising the importance of (a) assessing horticultural competencies, strengths and existing infrastructure; (b)aligning systematic conservation priorities and global need; (c) amplifying impact through partnerships; (d) developing research initiatives and expanding mission-aligned work; and (e)leveraging audiences. The article concludes by emphasising the importance of collaborative partnerships, avoiding mission creep through maintaining a strategic focus and understanding that a continuum mindset is essential. Longwood’s work, focusing particularly on terrestrial orchids, illustrates how a public garden can use this process to result in a successful and strategic impact-focused conservation horticulture programme that supports plant diversity
