Master Tree List

The following is a list of trees that are permitted to be planted in the City of Clinton parkways and/or right-of-way. It also includes trees not to be planted because of their lack of resistance to common tree diseases and/or pests or susceptibility to wind/storm damage.

This list may also be used by builders, homeowners, and business owners as a guide to appropriate trees to plant on their property in the Clinton, Iowa area. All trees being considered must meet the American Standards for Nursery Stock.

Most of the trees listed can be viewed at The Bickelhaupt Arboretum, 340 South 14th Street, Clinton, and are shown on their map of plantings and marked as a City of Clinton tree.
