Hortus botanicus Leiden The Hortus botanicus Leiden is the oldest botanical garden in Western Europe. It was founded by Leiden University in 1590 and the famous Carolus Clusius was its first director. Today the garden is open to the public and available for researchers as well as students. Research is performed on selected plant groups, including Orchidaceae, Annonaceae, Rutaceae and Cycadales. The systematic garden has been reconstructed in 2005 according to the most recent scientific insights and these living collections offer great research possibilities.

The objective of the research in the botanical garden is to get
