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.

For most grocery stores, external quality standards require that premium mandarins be orange, unblemished, and large. Thus, for consumers to differentiate among the premium mandarins on any dimension other than price, additional positioning attributes must be evaluated. This study considered consumer preferences for price ($2.18/kg, $4.39/kg, or $15.41/kg), packaging (1.36 kg of loose fruit, 1.36-kg bag, 2.27-kg box, or 0.23-kg clamshell with peeled fruit sections), type of mandarin (clementine, satsuma, tangerine), shelf life from the day of purchase (3, 14, or 31 days), and vitamin C content (with or without a label stating high in vitamin C). A conjoint survey was conducted in four grocery stores located in Birmingham and Montgomery, Ala. In total, 289 respondents used a 7-point intention-to-buy scale to rate photographs of 16 product profiles. Six market segments were identified, based on maximal similarity of preferences within each segment and maximal differences between segments. A simulation was conducted of the effect that an introduction of peeled-and-sectioned satsumas would have on the market share and gross revenue of other mandarins. This product showed great potential, but should be offered in a product mix that includes the loose form as well. Labeling for vitamin C was preferred by all segments, but did not contribute much to the intention-to-buy rating. Awareness and recognition of satsumas needs to be addressed in promotional campaigns. The longest shelf life was the first choice of almost half the respondents.

Fresh and processed tomato (Lycopersicon esculentum) consumption has increased 40% in the United States over the last two decades. Through better breeding, fresh tomatoes now are marketed in different forms, sizes, colors, and flavors. However, little published information exists concerning consumer demand, preference, and demographic characteristics related to fresh tomato consumption. Taking advantage of a high percentage of Internet use in the U.S., two web-based surveys were released to approximately 6000 e-mail addresses reaching people in every region of the U.S. The surveys contained a total of 61 questions, including 50 digital images of five types of tomatoes (cherry, grape, cluster, plum, and regular slicing) with combinations of three additional factors (price, lycopene content, and production style) and demographic information. Among 389 respondents, 76% preferred and purchased slicing tomatoes in the 4 weeks prior to the survey. These were followed by grape/mini-pear (42%), plum (36%), cluster (27%), cherry (25%), and yellow slicing tomatoes (4.4%). Overall, production method (organic vs. conventional) had low relative importance in comparison to price and tomato type. However, younger participants (<age 38 years) placed more importance on production method. Participants between ages 39 and 57 years were the most price-sensitive, and female were less sensitive than males. Younger participants (<age 38 years) were less price-sensitive and placed more importance on the other attributes (production method, lycopene content, and tomato type).

Two surveys were conducted to determine characteristics important in containerized edible flowers that could be sold in retail outlets. Self-selected participants at Bloomfest at Cobo Hall, Detroit, were assigned to one group that rated the importance of attributes such as color of pansy (Viola ×wittrockiana Gams. `Accord Banner Clear Mixture'), color combinations, container size, and price. Participants assigned to a second group rated color, color combinations, and container size. Flower color was allocated the most points in the purchasing decision (63% for the first group and 95% for the second), with a mixture of all three colors (blue, yellow, and orange) being the most desirable. Responses were subjected to Cluster Analysis (SPSS Inc., Chicago), which resulted in the formation of three distinct groups. The groups were labeled “Likely Buyer” (those who had eaten and purchased edible flowers before and rated characteristics of edible flowers favorably); “Unlikely Consumer” (those who had eaten edible flowers before and had rated characteristics of edible flowers unfavorably); and “Persuadable Garnishers” (those who had not eaten edible flowers before, but were very likely to purchase edible flowers for a meal's garnish).

Some consumer preference studies show that red is the most popular flower color. Most data analyses were univariate. Conjoint analysis allows simultaneous determination of attribute preferences without all alternatives being shown. Our purpose was to determine consumer preferences for geranium flower color, leaf variegation, and price simultaneously using conjoint analysis. Two-hundred and four consumers shopping at two Montgomery, Ala., garden centers in Apr. 1993 rated 25 composite geranium photographs. A lavender geranium, `Danielle', with green and white leaf variegation priced at $1.39 was most preferred. Flower color was most important in the purchase decision, followed by price. Leaf variegation was a minor consideration in the purchase decision.
