Systematics Section


The systematics section shows plant families according to their relatedness, and displays herbaceous plants that are able to grow in our climate. It gives insight into the variety of forms of vascular plants and their relation to each other. Every organism that exists on Earth today is the product of a long evolutionary process driven by natural selection, which creates new adaptive traits that are genetically defined. Worldwide, nearly 250,000 flowering plant species have already been described. Systematics has the goal of developing a straightforward and comprehensive classification system, and of describing the direction that the evolution of organismic traits has taken in each single case. For this purpose, all species features and all available information are considered in systematic descriptions.

Currently, evolutionary relationships in the plant world are being checked and updated through modern genetics technology. With this new information, there have been a number of changes and corrections to the evolutionary tree. For pragmatic reasons, a garden like ours with nearly 10,000 species has to keep a relatively conservative arrangement in naming and systematics until things are more or less sorted out.

Woody plants are also planted in related groups and are thus also a part of the systematics section. In the arboretum, they are principally grouped according to family and genus at various places throughout the garden.
