Right by my apartment, I can't help but come here often. It's situated right around the historic La Brea Tar Pits. One needs to spend an entire day here. Also love their magazine/book store.
Robert Irwin spent 4 years designing what he called "a sculpture in the form of a garden, which aims to be art". More than 500 varieties of plant material are used, and the selection is always changing, as testaments of what Irwin itself said: "art doesn't reside in the object but in the moment."
