On view
John Grade’s Union hangs roughly 100 feet between eight trees in the Washington Park Arboretum: two structures of cast resin framed in wood, enlarging the cellular patterns of two broken cedar leaders. Thousands of cupped forms hold rainwater, and the added weight shifts the upper structure against the lower.
The work
The installation is long-term but temporary; no removal date has been announced.
Before you go
Rain collects in the suspended cups and changes the work's shape; it looks different in wet and dry weather.
