ere is a great deal of research which demonstrates that living near nature has beneficial effects on wellbeing (e.g., Kaplan and Kaplan, 1989; Kaplan, 2001; Leather et al., 1998), that exposure to natural scenes has positive effects on physiological arousal and health (e.g. Bodin and Hartig, 2003; Hartig, Evans, Jamner, Davis and Garling, 2003; Ulrich, Simons and Miles, 2003; Parsons, Tassinary, Ulrich, Hebl and Grossman-Alexander, 1998) and on cognitive functioning (e.g. Kaplan and Kaplan, 1989; Hartig, Mang and Evans, 1991). There is, however, very little research which specifically examines the environmental features that promote restoration. And yet some research has shown a difference in perceived restoration with different vegetation types. White and Gatersleben (2011), for example, found that participants reacted differently to particular types of plants on green roofs, finding tall, flowering, meadow plants more restorative than shorter, succulent plants. This research examines the role of flower colour on restoration. According to the Flowers and Plants Association (2008) around 2 billion pounds are spent annually in the UK on cut flowers. And there is some evidence that people respond positively to natural scenes with flowers (e.g., Kaplan, 2007; Todorova et al., 2004). Very little is known, however, about how the colour of flowers affects people. Wexner (1954) found that people readily assign moods to colours, such as serene for blue and exciting for red. And garden designers and those in similar fields use colour in order to evoke particular moods in the viewer. An experimental study with undergraduate students at the University of Surrey examined the effect of flower colour in gardens on environmental restoration. Participants were asked to imagine that they were mentally exhausted and in a negative mood. They were then asked to imagine walking through a garden shown in a photograph. The photographs showed either blue/purple, yellow/green, or red/pink flowers. Analyses were conducted to examine whether preferences, affective quality and restorative effects were influenced by flower colour and whether this varied depending on people's attitudes towards the different colours.
