As a supplement to the Hildegard exhibition in the neighboring Museum am Strom, the garden showcases numerous plants that Hildegard described in her natural history ("Physica"). In this significant collection, the learned Benedictine nun described nearly 300 herbs, shrubs, and trees along with their (healing) effects on humans. Unfortunately, the work has only been transmitted in late medieval copies, so today no one knows the "original text" of Hildegard of Bingen. The didactically structured Hildegarden presents the "Book of Plants" and the "Book of Trees" from the "Physica" in a total of 15 themed beds and 8 individual beds.

In the small garden, a problem is addressed at the "Spring Fountain" that many popular writings on "Hildegard Medicine" tend to overlook: The "Physica" has only survived in late medieval copies, which is why no one knows the "original text" of Hildegard.
