She had a fast, expressive style like
John Singer Sargent and was known for her seascape and landscape paintings. Her works have been sold for more than $44,000. Roberts exhibited her works in the United States and in Paris. She was discouraged, though, that her work was not accepted for exhibition in major galleries, few of her paintings sold, and she was not accepted as a member of Boston's Copley Society.
Artist In 1899 or 1900, she returned to the United States. Roberts worked a full workday painting landscape scenes from Normandy, France or paintings with religious themes in the family's apartment in New York or house in Philadelphia. She exhibited paintings made in Europe at the Pennsylvania Academy, where she won a prize for her landscape painting, and at Lindsay's Gallery in Philadelphia in 1899. She also exhibited
The Green Gown,
Types of the Black Forest, and ''My Grandmother's Birthday''. Her mother died in 1900. In 1902, Roberts founded the Jennie Sesnan Gold Medal at the Pennsylvania Academy of the Fine Arts, for the best landscape. The Doll and Richards Gallery in Boston exhibited her portrait paintings of Frank B. Sanborn, an educator, and Judge John S. Keyes. Roberts sent her works to galleries and museums in major United States cities. In 1908, the
Detroit Institute of Arts held an exhibition of 30 of Robert's seascapes, some of which included playing children and families. Her paintings were exhibited at the
Indianapolis Museum of Art in 1908, 1910, and 1914. In 1911, she exhibited at
The Plastic Club in Philadelphia. During World War I, Roberts supported the war effort by donating some of her paintings, including those she painted of women gathered to sew clothing at the First Parish Church of Concord. The women were making clothing for refugees who had fled their homes in Belgium to England. A field ambulance was purchased from the $10,000 () she raised. It was used at battles in France. Due to physical examinations, she was unable to join the Red Cross as she desired.
Concord Art Association Roberts founded and funded the
Concord Art Association in 1917 and for 10 years managed its exhibitions. The purpose of the organization was to promote and encourage art and hold art exhibitions in Concord. She purchased the John Ball House in 1922 and hired architect
Lois Howe to renovate the building for its use as the Concord Art Centre, the original name of the organization. The second and third floors of the house built in 1750 were remodeled for gallery space and a great hall. A sky-light was installed to provide natural light for the gallery. The grand opening was held on May 6, 1923, with sixty painters and eighteen sculptors from Europe and the United States in attendance. Among the noted artists were
Claude Monet,
Robert Henri,
Mary Cassatt, and
John Singer Sargent. ==Personal life==
