Welcome to the History House Heirloom Gardens. The gardens are available to visitors throughout the year. The Heirloom Gardens showcase examples of old fashioned plant materials that would have been available to New England gardeners during the middle 1800’s. They include five plant materials common to old fashioned gardens: Peonies, Iris, Day Lilies, Phlox, and Hostas. Garden signage lists each plant’s botanical and common name and is referenced to an on-site Heirloom Garden Guide, organized alphabetically by a plant’s botanical name, family, and common name.
