Ted Stanley Hubbard, a Montauk landscaper who was inspired by the natural world and all things Native American, died on Monday in Montauk. Mr. Hubbard, who was 49, was “a free spirit,” his family said, who had traveled across the United States and into Mexico. He settled for a time near Gardner, Colo., where he volunteered at a wolf sanctuary, picked sage, lived in a yurt, and embraced a simple life.
