Beuys planted 7000 oak trees throughout the city of Kassel, near Düsseldorf (for Documenta 7, a yearly exhibtion. Each of the trees were paired with a large basalt stone, which were piled up on the lawn in front of the Museum Fridericianum – as the trees were planted so the pile of stones shrunk and shrunk. Beuys work was seen locally as a move towards green urban renewal, it took five years and has spread to other cities around the world such as New York.
The planting / re-planting in a new place relates to my own practise. I like the relationship between the partly industrial shaped rock and the completely natural tree.
