Lois Weinberger's 'Wild Cube' is a significant artwork featured in the Belvedere's collection. It consists of a large iron cage housing a diverse array of spontaneously growing plants, acting as a commentary on urban nature and the museum space itself.
Lois Weinberger's 'Wild Cube,' created in 2011, is a notable installation that explores the concept of ruderal species – plants that thrive in human-altered urban environments, particularly on abandoned or disused land. The artwork itself is a substantial iron cage, measuring 400 × 500 × 1200 cm, within which various trees and plants, such as elm, birch, white poplar, and Norway maple, grow rankly and without control, their branches extending through the bars. Weinberger conceived of this piece as a critical counterpoint to the sterile, conventional 'white cube' gallery space, inviting contemplation on the relationship between nature, urban development, and the institutional context of art display. The work is part of the Belvedere's permanent collection and is housed in the Sculpture Garden of Belvedere 21.
