Even though it may seem hard to believe, California for much of the twentieth century and periods before was a large agricultural zone. Areas like “Orange County” and “Lemon Grove” were named because of the large commercial agricultural operations that occurred in those areas. As a matter of fact, Disneyland was constructed on one hundred and sixty acres of land that was occupied by orange groves and walnut trees. While most of this land has been swallowed up by urban development, large agricultural zones remain today in the Central Valley, and through the Coachella Valley regions. While a number of state parks in California cover the historical heritage of these agricultural ventures, San Diego is also home to a yearly agricultural spectacle of flowers at the Carlsbad Flower Fields.
