Adding Green Space to MoMA With Tropical Terrariums

“We are not keen on all kinds of modern art, but this is brilliant,” said Laura Casado, a visitor from Valladolid, Spain, who was on vacation with her husband, Javier. On Monday afternoon, while Mr. Casado was busy photographing the terrariums, Ms. Casado explained, “My husband especially loves things that grow.”

These hybrids of art and urban-dweller’s garden make up the small exhibition “Nocturne of the Limax maximus,” running through Feb. 28. They come from the New York artist and landscape designer Paula Hayes, who has been blogging about the project on MoMA’s Web site, moma.org.
