A high percentage of fresh flowers sold are consumed as gifts in many countries, such as Taiwan, Japan, and the United States. As gift consumption is so important for the sales of fresh flowers, consumer behavior in floral gift giving is investigated in this research. This study explored the consumer decision to purchase fresh flowers as a romantic gift for Valentine’s Day based on 1) relationship stage, 2) affection, and 3) satisfaction with the relationship. The statistical results, based on the data of 366 valid questionnaires collected from a self-administered questionnaire survey, showed that the relationship stage of “personality need fulfillment,” the affection of “passion,” and relationship satisfaction significantly influenced the consumer decision of whether to purchase fresh flowers as romantic Valentine’s Day gifts. Consumers were more likely to buy their intimate partners fresh flowers when they perceived their personality need, such as the need of being loved, was fulfilled in the relationship. When strongly passionate about that relationship, they tended to give fresh flowers in conjunction with other gifts. However, when consumers were more satisfied with their romantic relationships, they were less likely to buy their intimate partners fresh flowers. The study results have valuable implications for florists’ business alliances and advertising campaign development for promoting floral gifts efficiently.
