The middle of winter provides a wonderful opportunity to learn more about the vast collection of trees in the Arboretum. Our Spring Grove horticulturists will lead a winter tree identification walking tour through the historic grounds. The tour will originate at the Historic Office, located just inside and to the right of the main gates. Dress for the weather. Registration is required and will open December 15, 2023 at NOON. Your $5 donation will go to the Heritage Foundation to further efforts in education, preservation, and community outreach.
