Cut flowers are a sizeable commodity in California. Last year, according to the U.S. Department of Agriculture Crop Reporting Board, the three major greenhouse species alone—carnations, chrysanthemums, and roses—were valued in excess of $83 million at the nursery. In addition, about 50 other species, including field-grown, accounted for perhaps another $50 million. It appears that most of these flowers were initially selected for commercial culture for reasons other than flower productivity.
