Kirchberg Arboretum - Autumn colors, acorns and beechnuts

A day in nature - Arboretum Kirchberg

Guided tours through the parks of the Kirchberg Arboretum are offered once a month from April to October. Explanations about plants according to the seasons are provided by Thierry Helminger, a botanist at the 'natur musée' and the head of the Arboretum.

Autumn colors, acorns and beechnuts

When the leaves change color in autumn, it is also the time when acorns and beechnuts fall. Did you know that you can recognise the different oak species by their acorns? Join biologist Thierry Helminger for a botanical walk through the park.
