In Basel, the artist planted several apple, cherry and kiwi fruit trees, which grew through a roof structure by the Swiss sculptor Reto Steiner. A literal intervention of nature into the space of art (albeit in domesticated form), the piece asks what it means for one work to be parasitic in relation to another, teasingly suggesting the inseparability of artworks from the natural ecologies and materials from which they come. The work is ongoing and will come to its completion in five to seven years, once the first ripe fruit rolls down the structure.
