Tree gardens embody the exuberance of the forest because they are closely planted and their collective mass overtakes their individual character. Because of their structural density, they animate the sunny lawns and gathering spaces to which they act as walls. And, while they create memorable landscapes for walking, talking, interacting and just being—they simultaneously improve water and carbon retention. Their goal is regeneration, whether they are constructed from trees of the same age and same species, or a diversity, such as a generation of new trees planted within existing trees.
