In Miller v. County of Kern (1902) 137 Cal. 516, the Supreme Court determined that alfalfa was not within the "growing crop" exemption. The court reasoned that alfalfa is a perennial plant which, when properly maintained, produces annual hay crops for an indefinite number of years. ( Id., 137 Cal. at pp. 524-525.) It was decided that alfalfa was not a growing crop: "As a hay crop, it is unlike wheat or barley, sown for hay, which produces but a single annual crop and no more." ( Id., at p. 525.)
