It takes its name from Spring Garden Avenue, which follows the floor of the valley that separates the two adjacent hilltop neighborhoods of Spring Hill and Troy Hill.

These initial residents of Spring Garden worked in slaughterhouses, rendering factories, and tanneries located in this valley neighborhood.
