The Hortus Botanicus Leiden is the best place for a peaceful walk through greenhouses and gardens. This is where Carolus Clusius cultivated the first sizable tulip collections in Europe and where Philipp Franz von Siebold introduced about 700 hitherto unknown plants from Japan and China.
Green treasury
Today, this green treasury serves as a home to rare plants from Southeast and East Asia, Southern Europe and Southern Africa, some of which have become extinct in the wild. It is a major international research center for scientists studying plants from the renowned Hortus collection. Plants have been collected and cultivated in these gardens and greenhouses for over four centuries, not just for scientific purposes but also to be enjoyed.
