Botanischer Garten der TU Darmstadt, Technical University botanical garden in Darmstadt, Germany

The Botanical Garden of TU Darmstadt is a research facility in Darmstadt featuring open cultivation areas alongside climate-controlled greenhouses. The grounds display plants from across the world, organized by their native regions and growing requirements.

The garden dates to 17 June 1814, when Grand Duke Ludwig I of Hesse-Darmstadt approved building advisor Johannes Hess's plan to drain the foul-smelling palace moat and create a botanical garden on the reclaimed ground. After moves to the Herrngarten, Mercksplatz and Wilhelminenplatz, it settled in 1874 on the Achensmühle site east of the Woog, bought for 35,700 guilders. It joined the Technische Hochschule Darmstadt in 1897.

The garden hosts the art and design exhibition "Art of Eden", held there for several years, and occasional music events. Its street, Schnittspahnstrasse, recalls the Schnittspahn family of gardeners: Johann August tended the first garden from 1814, and Georg Friedrich became its first director in 1855.

The garden opens daily and admission is free; it lies at Schnittspahnstrasse 1–5 in Darmstadt-Ost, near the northern edge of the Odenwald. About 4.5 ha of open ground and 1,300 m² of greenhouses are best explored on foot, with the arboretum and alpine garden outdoors and the tropical collections under glass.

The garden's oldest woody plants trace back to Leopold Dippel and garden director Peter Schmidt, who from the 1870s assembled a collection of foreign trees that is still considered important today. Their arboretum now covers 1.5 hectares within the roughly 4.5 hectares of open ground.
