This Juneteenth, we reflect on witness trees, a concept featured in the "Sheltering Branches" thematic section of the exhibit HABITAT, from the Smithsonian Institution Traveling Exhibition Service.
A "witness tree" is one that was present during a key event in American history. While the Garden cannot (yet) claim one of these trees on its 132-acres, we know of a witness tree that is not very far from here.
Shortly after the Emancipation Proclamation arrived in Galveston on June 19, 1865, enslaved people of the Palmer Plantation gathered under a large live oak in what is now Missouri City, where they learned that they were free. That witness tree is still growing in Freedom Tree Park to this day. and you can read more about it on one of the Sheltering Branches panels under the shade of our Bayou Oaks.
When we plant trees, we choose to participate in a history that will go on and on. For instance, we wonder what these trees overlooking Sims Bayou might one day witness, and just as importantly, we encourage you to think about what something you plant might witness in the future?
