At the Getty Central Garden with Robert Irwin

Though Irwin was criticized for his plant selection in the water-bound azalea maze, he still defends his choice. “I was looking for a plant that had certain properties, and the azalea kept coming up as a possibility,” the artist said, later adding: “There is a famous azalea grower in Altadena called the Nuccio Brothers. For four generations, that’s all they’ve done is grow azaleas. They told me which azaleas are going to do [what], which peat moss to get, how they should be grown. I did my homework.”
