Rosa M. Towne was born in about 1827, the daughter of John Towne, a wealthy businessman, and Sarah Robinson Towne. Her siblings included artist Ann Sophia Towne Darrah, educator Laura Matilda Towne, and engineer John Henry Towne.

Towne is best known for her botanical watercolors. Between 1888 and 1898, Towne completed 73 paintings of 182 plants, all of the plants mentioned in the works of Shakespeare.
