On Arbor Day, April 28,2023, we will be celebrating the legacy of the founder of the Nannen Arboretum, John Ploetz. His children are donating 2 trees for the Arbor Day planting and are hosting an Open House as part of the meeting. Beginning at 11:00 am with the Annual Meeting and Arbor Day proclamation/planting, we will then transition to an Open House around noon. Posters and photographs from the early days of the arboretum will be displayed. Several of the Ploetz and Nannen families, as well as some of the original members of the arboretum will be available for conversation and reminiscing. Refreshments, sandwiches, cookies and drinks will be provided during the Open House which will last until 3:00 pm. Everyone is welcome and encouraged to attend.
