Do consumers prefer certain combinations of edible-flower species and colors over other assortments? Two hundred and sixteen people were self-selected for a survey at a Michigan flower show to rate 15 photographs of edible flowers arranged in 0.24-L, clear, plastic containers. Each container had either an individual species or combinations of Viola tricolor L. `Helen Mount' (viola), Borago officinalis L. (borage), and Tropaeolum majus L. `Jewel Mix' and `Tip Top Apricot' (nasturtium). To determine what color(s) of nasturtium participants would prefer, containers held either orange and crimson, peach and cream, or a combination of all four flower colors. Participants rated photographs using a semantic differential on a 7-point Likert scale (7 being the highest rating) based on their likelihood to purchase each container of edible flowers to serve to family and friends in a meal. Participants were asked an additional 21 questions regarding their attitudes about edible flowers, gardening habits, dining habits, and several demographic questions. Responses were subjected to conjoint analysis (SPSS Inc., Chicago). The addition of other species to nasturtium (viola, borage, viola, and borage) had a greater relative importance (53%) than the color of the nasturtium (47%). A mixture of all four nasturtium colors (peach, cream, orange, and crimson) was awarded the highest utility (0.091). Peach and cream nasturtiums or containers that did not contain any nasturtium flowers at all were least preferred (-0.070 and -0.083 utilities, respectively). Mean ratings that participants assigned to containers of edible flowers supported these utilities. The container assigned the highest mean rating included nasturtiums of all four colors, yet 66% were unlikely to purchase any container with 10% insect damage. Differences in preferences were noted using selected demographic characteristics such as age, gender, and income.
