Now a third-generation company with seven locations in New England, Winston Flowers began as a father-son team, with a pushcart parked in front of the Ritz-Carlton hotel on Newbury Street in 1944. Winston Flowers prides itself on their close relationships with growers, and they also highlight local farms, particularly from late summer to early fall, when favorite flowers like sunflowers, peonies, and lilac are in season. The Financial District shop is open weekdays only; the other Boston location, the original one in the Back Bay, is open seven days a week.
