This historic property overlooks Narragansett Bay with expansive grounds for residents. The location of this property renders it unique in its landscape and tree collections. Harbor House’s proximity to the water exposes plants to harsh winds and salt spray. Some mature specimens thriving in these harsh conditions include an extremely old Yew Tree, and a massive London Planetree, likely original plantings from the 1850s when the Auchincloss house was built.

The mission of the Harbor House Arboretum is to be consistent in replanting efforts to maintain the existing tree collection and canopy, as mature trees reach the end of their lifespan. In addition to maintaining the property’s green diversity, the mission includes encouraging resident engagement in the landscape. Harbor House is excited to host a Newport Arboretum Satellite Nursery with a special collection of rare coastal native trees.
