Visitors can step inside a tree sculpture, climb on roots, and discover the hidden systems that sustain forests when Tree Dimensions, The Morton Arboretum’s exclusive new interactive outdoor art exhibition opens May 22, 2027.
The exhibition will feature five large-scale sculptures ranging from 11 to 20 feet tall that create colorful, immersive spaces for exploration, play and reflection.
Inspired by the diversity of shapes, textures, and colors found throughout trees—from bark covered in moss and lichens to changing oak leaves and intricate root systems—the sculptures offer a range of experiences while revealing how trees support biodiversity, benefit communities and enhance the world around us.
Four sculptures will be situated along the Arboretum’s Conifer Walk, a paved, ADA-accessible path near the Visitor Center that winds through a diverse collection of cone-bearing trees and shrubs from around the world. The fifth sculpture will stand on a hill visible from Interstate 88, creating a striking landmark across the Arboretum’s landscape. It can be viewed from nearby areas and reached via an inclined, chipped hiking trail.
The five Tree Dimensions sculptures were created exclusively for the Arboretum by Chilean visual artist Rommy González, and produced by art agency Millecent.
Born in Santiago, Chile, Rommy González is a Berlin-based visual artist whose practice draws inspiration from botany, geology, microbiology, and fungi. Her colorful murals, installations, and public artworks have been exhibited across Europe, North America, Latin America, and Asia.
Installation of Tree Dimensions will begin in spring 2027. The exhibition will be included with Arboretum general admission and remain on view through March 2029.
