What object inspired the classic gallon pot after World War II?

The classic gallon pot took inspiration from the design of a salvage can, which was a practical and widely recognized object during and after World War II. Salvage cans were used for the collection of various materials, providing a convenient vessel for both storage and transportation. Their shape and size proved to be well-suited for growing plants and holding soil, leading to the adoption of this design in horticulture. This transformation in product design reflects how everyday materials and ergonomic considerations can influence gardening practices and the tools used by horticulturists. Understanding this connection provides insight into the ways in which utility and innovation in material usage can enhance both functionality and efficiency in the gardening and horticulture industry.
