What U.S. state produces the most roses for Valentine's Day?

California is the answer. California flower farms and greenhouse operations make the state a major part of the American flower industry, especially for cut roses and other Valentine’s Day flowers. The state’s climate, agricultural infrastructure, and controlled growing environments support large-scale flower production, while Valentine’s Day creates one of the biggest annual demand spikes for roses. Many roses sold in the United States are imported from countries such as Colombia and Ecuador, so California should be understood as the leading U.S. state tied to domestic rose and cut-flower production rather than the source of all Valentine’s Day roses sold in America.
