The Museum Garden 125 years

The museum's first botanist Jørgen Brunchorst wanted to show domestic species and an exhibit of the systematic groups of plants. The original plan for the garden has not been found, but a map from the museum's 75th anniversary book (1900) shows how the garden was laid out with curved paths. Very few of these remain today, only in "Gamlehagen" (the old garden). The Museum Garden was listed as protected in 2013.

The greenhouse consists of three sections: A ten meter high palm house in the middle, with two side wings, one tropical and one cooler. Originally, the house was a gift from Conrad Mohr, a merchant, and it came from Germany as a building kit. It was officially opened in 1901. The area by the museum's south wing was originally a marshy area or a pond. This was filled when the garden was being constructed. Initially, the area consisted of a lawn and rounded flower beds and a menhir (standing stone). Later, the bust of Armauer Hansen was moved here.

One of the oldest and among the most interesting of the garden's trees is the japanese angelic tree, which was planted in 1898 by Brunchorst. It stands by the fence along Olaf Rye's vei and flowers in late September, for the first time in 1901, with large inflorescences that are very popular with bees and other insects. It has long root shoots with large thorns and has been known as "the devil's walking stick".
