Flowering Plant Growth and Cultivation

The objectives of this study were to survey Midwest consumers to assess their willingness to buy alternatives to Impatiens walleriana given the confirmed presence of Impatiens downy mildew (IDM; Plasmopara obducens ) in Michigan landscapes in 2012. An Internet survey queried consumers from four states (Illinois, Indiana, Michigan, and Ohio) and questions consisted of likelihood to buy, purchasing characteristics considered, impatiens purchases in 2012, and demographic questions. Roughly 500 participants per state responded and almost three-fourths (73.8%) of respondents said they planted impatiens in their landscape in 2012. Of the 16.4% who said their plants did not look healthy at the end of the growing season, 69.3% self-identified the plant as having IDM symptoms. Purchasing characteristics that had the highest mean scores were bloom period, flower color, and longevity, whereas the lowest mean scores were for compact shape with no spindly growth, fragrance, and locally grown. Three impatiens alternative species were acceptable alternatives (scored a positive utility in the conjoint analysis) for shade-tolerant species. Begonia semperflorens was the most preferred followed by Browallia speciosa and then Impatiens hawkeri . Solenostemon scutellarioides was the least preferred. Three impatiens alternative species also scored a positive utility in the conjoint analysis and would serve well for partial shade-tolerant species. Heliotropium arborescens was the most preferred followed by Salvia splendens and then Lobelia erinus . Hypoestes phyllostachya and Iresine herbstii were preferred least as impatiens alternatives. The attribute with the highest relative importance was species for both conjoint analyses, whereas the price attribute was the least important.
