Grasses of a Thousand Colors is a disturbing and anomalously beautiful play that explores the role of human beings in nature and the role of nature in human beings, sexuality being as Wallace Shawn says, “nature’s most obvious footprint in the human soul.” The play’s central character is a doctor who believes he has solved world hunger when he figures out how to rejigger the metabolisms of animals to tolerate eating their own kind. This has unexpected consequences. The play tells a story about the doctor, his wife, and his lovers, that is also a story about human beings and animals and the planet we live on.
