In this article we consider the use of visual images to assess perceptions of plants. Using data drawn from a Swedish study we review our choices regarding the type of image used, and the responses they provoked. Furthermore, we consider these choices in the light of other studies, propose a tentative model of levels of seeing, and call for further research. In sharing our methodological challenges with the research community, we wish to contribute to current discussions in plant awareness studies. More specifically, to the development of a visual prompt item that is not explicitly connected to knowledge. Thus, the main contribution of this article is to visual research methods in relation to plant awareness studies.
