There are over 16,000 accessioned plants at the Arboretum. An accessioned plant is one that is part of the Arboretum’s official collections. It has a unique identifying number, and careful records are kept about the plant, including its name, age, who collected it, and where it came from.
Much of this information is printed on plant labels, which can be found on branches, tree trunks, and stakes throughout the landscape.
