Letha Wilson Wall in Blue Ash Tree. Part of an exhibition called ‘Nature Unframed’ in 2011 it puts nature very literally on a canvas by a bringing the gallery wall to the tree.
This piece is an interior wall built inside and alongside a Blue Ash Tree at the Morton Arboretum in Lisle, Illinois (outside of Chicago). It was built with a wood stud structure and then faced with ordinary sheetrock, drywall compound, and paint. The wall faces almost due west so from about 12:30 on the sun casts shadows on the wall from the tree limbs and leaves. This particular tree is fairly late to leaf out, so the piece will change considerably throughout the season.
