Product design, through its sensory attributes, plays a major role in product perceptions and its understanding by consumers. It conveys rich symbolic associations and contributes to shape brand image and its personality traits. A flower is a singular product, expressive and particularly evocative by its design. Flowers can be conceptualized as brands possessing humanlike traits. An experiment on two flower varieties, tulips and roses, with 509 people, shows that shape (pointed or rounded petals) and brightness (pink for the light color or purple for the dark color) influence a flower brand’s personality. Sincerity, excitement and ruggedness are associated with tulips; sophistication is linked to roses. Dark colors and sharp forms are related to competence and excitement. Then, the human personality accentuates dominant traits identified, agreeableness dimension in particular. The results confirm the power of design to shape consumer perceptions and the strong link between consumer profile and brand personality.
