In 1902 Connecticut held a convention in Hartford to consider updating the State Constitution. Each delegate to the convention received a Pin Oak (Quercus palustris) seedling. Windsor delegate D. E. Phelps planted his oak seedling on this spot on the town green in front of the Windsor Public Library. One hundred years later, in 2002, a survey showed that of the original 168 oak seedlings, only 74 had survived. At that time the Windsor Constitution Pin Oak tree measured 73 feet high and 117 inches in circumference. These trees have no relationship to the famous Charter Oak.The Abigail Wolcott Ellsworth Chapter, National Society of Daughters of the American Revolution, had placed a marker on the tree commemorating the 50th anniversary of the planting. In 2012 the group placed a new stone marker with a bronze plaque at the base of the Windsor Constitutional Oak in recognition of the historic planting 110 years before.
