The yearly summer festival is the main event in the botanic garden with numerous activities
and an interesting program for all age groups.
In mid-April starts the flowering season of the Handkerchief Tree. The exploration history
of this unusual tree is a good example of how important ornamental plants from China became in our gardens.
„Steppe plants“ is the main topic of the botanic garden in the year 2015. With guided tours, lectures
and excursions, we provide information on the biology and potential use of plants from steppe areas.
The distribution of Onosma arenaria in Germany is limited to the Mainz Sand Dunes.
In the botanic garden rare plant species are preserved outside their natural habit.
The Green School offers exciting projects dealing with botanical subjects designed for all age groups.
Thanks to the support of dedicated donors and friends, you can discover several works of art
in the botanic garden, like the „Tanzpartie“ by Eberhard Linke.
