Starting in the 17th century the collection was enhanced by plants, brought by merchants from the Dutch East Indies Company. There are over 6,000 trees and plants, some of the varieties are even in danger of extinction.
In 1987 The University of Amsterdam stopped funding the gardens, and the gardens went through financial trouble. It was finally rescued thanks to private donations, but to maintain the garden to its highest standards, the city of Amsterdam assisted as well. There are two venues to hold events in, and can be rented out.
In the garden you will see the "Palm House." It was built in 1912, and contains a collection of cycads (a series of seedless vascular plants). You can also see the new greenhouse, built in 1993. This greenhouse has three different areas of climates. It contains a few benches spread out around the building, where you can take a short break.
