Where the Light Gets In - Beal Botanical Garden
Installation
2025
The Amur cork tree (Phellodendron amurense), is a non-native and invasive species in the Midwestern United States. An invasive species is categorized as a species that is both non-native and whose presence has negative impacts on surrounding native plants and wildlife. While there are many non-native species in the Beal Botanical Garden, the Amur cork specifically has been slated for removal due to its ability to outcompete native tree species such as oaks and hickories, through the spreading of seeds via berries.
Three Amur corks were known to exist in the garden, with two being quietly removed in the night (stumps and all) to the dismay of several garden volunteers. One Amur cork remains and is set to be removed, but there are some barriers to consider. The tree is easily recognized due to its central location, iconic shape, and presence in photos and promotional materials for the garden. Additionally, the tree provides ample shade for events that take place in the garden.
As of August 6, 2025, another Amur cork was identified in the garden along the river.
As part of the ongoing Where the Light Gets In series, the tree will be marked with beams of light, designating its impending removal. By lighting the tree, visitors to the garden will be able to mourn the future loss of the tree.
