Fanwood is one of the smallest municipalities in Union County — a single ZIP, 07023, and barely more than a square mile of it. The Raritan Valley Line cuts the borough in two, and the 1874 Victorian depot beside the tracks, now the home of the Fanwood Museum, is the thing most people picture when they picture the town. The commercial life is short and walkable: South Avenue along the rail side, Martine Avenue running north to south across it, Borough Hall up on North Martine, the Fanwood Memorial Library on Forest Road, and the green space at La Grande Park and Forest Road Park where the borough's own gatherings happen. Almost everything a sender needs to know about Fanwood fits in those few street names — which is exactly why the addresses that go wrong here go wrong for a different reason entirely.
That reason is Scotch Plains. The township wraps around Fanwood on nearly every side, and a long list of shared institutions carry both names at once — the school district and the regional high school most visibly. Senders read a name with two towns in it and pick the wrong one for the label, or assume the two municipalities are one delivery area. They are not: they are separate municipalities with separate street grids, and a driver working from the wrong town name can end up on a same-named road a mile from your recipient. Use the recipient's own town and street exactly as they gave it, and when an organization's name contains both towns, go by the building's street address rather than the name on the letterhead.
Two pieces of planning stay with you rather than with the florist. First, the receiving end: a gift sent to a workplace only lands if somebody there can accept it, so use the business name and your recipient's actual working hours, and if they commute on the Raritan Valley Line, send to their real receiving address rather than the station or a guessed arrival time. Second, anything bigger than one arrangement: count the tables, size them, and decide who is going to place the flowers before you order, because a delivery date on an ordinary bouquet confirms a bouquet and nothing more — not the staffing, and not the building access a ceremony or a large coordinated setup needs. Those need a brief a florist has explicitly taken on. For everything else, a single vase arrangement carried into a Fanwood kitchen is complete on its own.
