In June 1893 Payne completed his contract and traveled to the United States. He arrived in New York, traveled to Chicago where he visited the World's Columbian Exhibition, then set out for Southern California. Upon arriving in 1893, he worked for a week picking apricots, then in July found a job as head gardener for Madame Helena Modjeska at "Arden." her ranch estate in Santiago Canyon of eastern Orange County. In his memoir, Life on the Modjeska Ranch in the Gay Nineties , he offers perhaps the best account of daily life on the Modjeska Ranch. It was there that he began his lifelong interest in California native plants, exploring the extensive natural areas surrounding the Ranch. In 1898, Payne left the employment of Madame Modjeska for a position with the Germain Seed Company. He remained with this firm for five years, becoming head of the seed department. He started his own business in 1903 when he purchased the Evans Nursery in Downtown Los Angeles. California native wildflower seeds and bulbs and native plants were the specialty of his plant nursery business. His nursery location moved several times before settling permanently on Los Feliz Boulevard in Atwater Village in 1923, a few miles north of downtown Los Angeles. The main nursery building was designed by architect Myron Hunt. Even in the early years of the 20th century, native habitats were being lost to agriculture and housing at an alarming rate in California. He urged the use of California native plants and lectured across the state on preserving the wild flowers and landscapes native to California. In 1907 Payne married Alice Noyes in San Francisco, a marriage of 56 years. In 1915 he laid out and planted 262 species in a wild garden in Exposition Park, in central Los Angeles. In 1926 he helped to establish the Blaksley Botanic Garden in Santa Barbara, In 1939 he created native plant garden with 178 plant species at the California Institute of Technology in Pasadena. He assisted Susan Bixby Bryant in 1927 with the siting and design of the original Rancho Santa Ana Botanic Garden in Orange County, and helped relocate the Garden to Claremont in 1951. In 1958 he helped create the native plant garden at Descanso Gardens in La Cañada. By the time he retired in 1958, Payne had introduced over 430 species of native plants to the public through his nursery. Theodore Payne died on May 6, 1963.
