At Paris Internationale, Pierre Portelli’s strategic camouflage targets the curtain of a window with the site-specific installation The Blue Garden (2021), turning an invisible, almost neutral threshold between the building and the exterior into an opportunity to discuss psychological boundaries with nature. The title reflects the exuberance of the appropriated traditional Chintz pattern lovingly imprinted with blue roses, a flower that does not exist in nature. The result of a recent genetic hybridization, the blue rose has come to symbolize the unattainable or the impossible in popular culture. However, in Portelli’s curtain a significant number of flies, similarly rendered in blue, have hacked the idyllic picture.
