Greenhouses to visit in the United States

The Verrière atlas lists 31 greenhouses in the United States, built between 1820 and 2024.

No country is better represented in the atlas. Most of America's great conservatories were born around 1900, often given to a city by an industrialist — Pittsburgh's Phipps bears its donor's name — and modelled on English precedents, from the Crystal Palace to Kew's palm houses. The 1960s then turned the United States into a laboratory of botanical modernism, with St. Louis's Climatron, the first geodesic dome used as a botanical greenhouse, and Milwaukee's Domes. Today's generation, from Longwood Gardens to Richmond, expands and modernises rather than replaces.
