Götterbaum
Until March 26, 2008, a -tall 75-year-old Tree of Heaven ("Ailanthus altissima") was a prominent centerpiece of the sculpture garden at the museum. The tree was spared by Noguchi when in 1975 he bought the building which would become the museum and cleaned up its back lot. "[I]n a sense, the sculpture garden was designed around the tree", said a former aide to Noguchi, Bonnie Rychlak, who later became the museum curator. By early 2008, the tree was found to be dying and threatened to crash into the building, which was about to undergo an $8.2 million renovation. The museum hired the Detroit Tree of Heaven Woodshop, an artists' collective, to use the wood to make benches, sculptures and other amenities in and around the building.
