Promisek at Three Rivers Farm in Bridgewater will participate in Connecticut's Historic Gardens Day June 23 from noon to 4 p.m.

Noted landscape architect Beatrix Farrand designed the historic garden for Dr. Frederick Peterson, a noted New York neurologist who entertained family, friends and clients on his 300-acre property he named Three Rivers Farm.

By the time Promisek purchased the property in 1978, the walled garden had been overtaken by decades of overgrowth, but the hardscape remained.

Promisek members cleared the brush to reveal flagstone pathways and stone around the garden, and a local resident and garden historian researched and rediscovered Farrand's garden plan.

Today, a team of garden volunteers maintains the garden, making every effort to stick to the original plan.

The garden is open the last Sundays of June and July from noon to 4 p.m. and by appointment.

The farm is at 694 Skyline Ridge Road.
