  • ILCA Nurseries Tree List

    The following list of trees is intended to assist buyers in their selection and purchase process. The list was prepared and reviewed by Illinois certified nurseries that are members of the Illinois Landscape Contractors Association (ILCA).

    The list is composed of trees commonly grown by local nurseries, and it will be subject to periodic review and revision as new varieties become available to producers. Not every genus or cultivar is reflected in this list, but rather the most common ones grown in nurseries to date.

    Trees that are in limited production are noted. These trees are harder to find either due to production difficulties or limited liner stock availability. Trees that are native to the Midwest are also noted as such.

    Buyers are encouraged to contact growers directly for assistance with selecting the appropriate trees for their planting projects.
