The Larz Anderson Bonsai Collection at the Arnold Arboretum in Jamaica Plain, Massachusetts is one of the premier collections of bonsai in the United States and includes a Hinoki Cypress over 250 years old.[1]
The Bonsai Pavilion where the trees are housed are part of the complex of buildings known as the Dana Greenhouses. The collection is on display from mid-April to the end of October. As the bonsai trees are deciduous, they are held in cold storage at temperatures slightly above freezing throughout the winter.
