Mary Vaux Walcott was born in Philadelphia, Pennsylvania to a wealthy Quaker family. After graduating from the Friends Select School in Philadelphia in 1879, she took an interest in watercolor painting. When she was not working on the family farm, she began painting illustrations of wildflowers that she saw on family trips to the Rocky Mountains of Canada.
