The living plant collections form the heart of the Hortus botanicus Leiden and serve as a vital resource for scientific research. By studying these collections, researchers can explore biodiversity in a unique way and conduct experiments on living material.

The research collection primarily focuses on the flora of tropical Southeast Asia, with special emphasis on certain plant groups, including:

• Carnivorous plants
• Orchids

These groups, along with the rest of the collection, are integral to ongoing botanical research at the Hortus.

Botanical history and heritage

With its long history, the Hortus botanicus Leiden has played a significant role in the development of botany as an independent science, separate from medicine. Over the centuries, several prominent botanists have contributed to its legacy, and the garden has been deeply involved in the introduction of plant species from around the world.

The Hortus’ archives and library hold a wealth of historical information. They offer insight into the evolution of botanic gardens and acknowledge the garden’s role in the colonial plant trade. Some of these archives are housed at Leiden University, while others are preserved at Naturalis Biodiversity Center.

The Hortus is committed to studying the history of botany by utilizing its own archives, those housed at other institutions, and the herbarium and alcohol collections stored worldwide.
