Garden wedding venues, by metro

Botanic gardens and conservatories publish ceremony-site rentals that are far cheaper than their full event packages. The catch is almost always a strict guest cap and a fixed time window.
101 listings across 20 metros. A metro only appears here when it has at least 3 verified listings that fit, so this list is shorter than it could be and every page on it is worth opening.
