Among the collectors with whom she competed was Edward Perry Warren, who supplied a number of works to the Museum of Fine Arts, Boston.
The Gardner collection includes works by some of Europe's most important artists, such as Botticelli's Madonna and Child with an Angel, Titian's Rape of Europa, Fra Angelico's Dormition and Assumption of the Virgin, and Diego Velázquez's King Philip IV of Spain.
While in Venice, Gardner bought art and antiques, attended the opera, and dined with expatriate artists and writers.

This duty is now performed each year on her birthday and alternates between the Society of St John the Evangelist and the Church of the Advent.
