The conservatory at Stonecrop Gardens in Putnam County, NY. I didn’t particularly want the woman with the camera in the picture but she didn’t look like she was moving any time soon and I was too lazy to wait. In any case there was no guarantee that she would not have been replaced by someone else…

According to this piece by the Hudson River Valley Institute:

The Conservatory at Stonecrop has four wings. Each wing has the ability to maintain a unique
environment with climate control systems. It was completed in 1997, and is used as a display house
in the winter and spring. At that time of year, the display house consists of non-hardy plants and various blooming bulbs, trees, and shrubs. In the summer, most of the plants are moved out into
the garden, so the Conservatory becomes a space for special projects.
