National Plant Collection Foundation
This foundation is an alliance of twenty Dutch botanic gardens. The aim among others is the preservation of the botanical heritage which is distributed over the various gardens. To do this efficiently each garden takes care of a number of plant families. By doing so the complete collection can be conservated, tracing omissions and avoiding doubles.
The other goals of the foundation are:
to contribute to scientific education and research, to support biological diversity, to promote education of nature and environment, to serve as a source of reference for horticulturists and to have an open eye for recreational aspects.
Plant families in the Botanical Garden of the TU Delft
The garden shelters 16 plant families and 1 genus, Lavandula, of the National Plant Collection. Moreover, a group called technical plants. The existence of this separate group is linked to the specific nature of the Delft Botanical Garden which from its beginning orients on economically useful plants, e.g. rubber, kapok, cocoa.
Burgers Zoo keeps a shadow collection of the Zingiberaceae and Musaceae.
