An early harbinger of the holiday season, the colossal white spruce fresh from Nova Scotia that will become Boston's Christmas tree is expected to arrive at the Boston Common with a police escort at 11 a.m.
The 50-foot-tall, 50-year-old tree will be placed near the visitors center on Tremont Street, the Boston Parks and Recreation Department said in a statement.
The tree was donated by Gary and Roseann Meisner of North Alton, Annapolis Valley, Nova Scotia, and was selected by Ross Pentz of the Nova Scotia Department of natural resources, the statement said.
Nova Scotia first started giving Christmas trees to Boston 39 years ago as a thanks for the city's response to a disastrous explosion of a munitions ship in Halifax Harbor in 1917. A train loaded with supplies and medical personnel headed from Boston to Nova Scotia within 24 hours of the incident, said the statement.
The official tree lighting, a classic holiday season ritual, will take place on Dec. 2 at the Boston Common from 6 p.m. to 8 p.m., according to the statement.
