The private country garden at a Long Lots Road home will be open for public tours Saturday under the Garden Conservancy’s “Open Days” program.

The garden at the Kiernan estate, 196 Long Lots Road, will be open from noon to 6:30 p.m. in conjunction with the conservancy’s launch of the book, “Outstanding American Gardens: A Celebration — 25 Years of the Garden Conservancy.” The volume showcases 50 gardens across the nation that the Garden Conservancy has helped save since 1989, according to publicity for the event.

The property, according to Garden Conservancy, “offers sweeping vistas encompassing many textures and layers of ornamental plants and trees. The land has been cultivated by Judith and Charles Kiernan along with a team of garden practitioners over the past 20 years. Original plantings have matured, offering a grand sense of scale throughout the space ...

“Today, the colorful space features an inventive combination of mature growth trees, perennials and annuals that combine to create a sense of balance and equilibrium between the stately home and the outdoor space,” the conservancy states. “Stonework, sculpted hedges, over-sized perennials, water and lush foliage punctuate the views and create strong focal points.”

Garden practitioners will be on hand to discuss the property with visitors, who can expect to see “a profusion of the garden’s many species of dahlias,” according to publicity.

Admission to the Kiernan garden is $7; children 12 and under are admitted free. Proceeds benefit programs of the Garden Conservancy. The event will take place rain or shine, and reservations are not required. Call 1-888-842-2442 or visit for garden details, travel directions and ticket information.
