The Continental Farm of Sahuarita plays a central role in town history. In 1915, worried about the possibility of a German blockade of rubber imports, Bernard Baruch, Joseph Kennedy and J.P. Morgan founded the farm along the Santa Cruz River with hopes of growing guayule: plants that provide rubber. The project was abandoned after the end of World War I, and in 1922, was sold to Queen Wilhelmina of the Netherlands. The Queen rented the land to cotton farmers, in what would be the primary crop for the following four decades. In 1948, R. Keith Walden relocated the Farmers Investment Co. (FICO) from California to Arizona, buying the Continental Farm lands from the Queen. In 1965, over fears of a fall in demand for cotton resulting from the advent of synthetic fibers, Walden switched his crop to pecans. Today, the FICO pecan orchard is the largest in the world, with over 6,000 acres and 106,000 trees.
