Early life and education
Perry was born in Havelock, New Brunswick, Canada on January 5, 1895. Her early education was in a one-room school. She received teacher training at Provincial Normal School  in Fredericton. After a short period of teaching, she attended Acadia University and received a B.S. in Biology with honors in 1921.

She became a U.S. citizen in 1938.

Career
In the summer of 1929, she spent a month collecting plant specimens on St. Paul Island (Nova Scotia) with Dr. Muriel V. Roscoe, leading to the production of a vascular flora of the island published in 1931.
