## 3 Discussion  
This study aimed to develop the sensory profile describing the perception and to find suggestions for the correlating chemical compounds of rose-scented _Pelargonium gravelens_ 'Dr. Westerlund' as a potted plant and stem cuttings by sensory and chemical analyses. The intention is to use these results as an input for a future study, where the chemical compounds will be quantified and to a higher extent be correlated to the sensory results as well as to health effects. It has been shown by [PERSON] et al. (2017) that the _Pelargonium gravelens_ 'Dr. Westerlund' elicited positive emotions and memories, as well as reduced the perceived stress among patients suffering from stress-related mental disorders. The results are supported by earlier findings, e.g., [PERSON] et al. (2018), who illustrated decreased anxiety when using the geranium essential oil, and [PERSON] et al. (2015), who demonstrated that the distinct notes of citrus and floral scent could support stress reduction. Findings such as these highlight the need to increase the understanding of the underlying factors explaining these perceived benefits and the physiological reaction that might reduce \begin{table}

stress. The impact of the volatiles on stress is to be further investigated when quantifying the chemical compounds found in _Pelargonium gravelens_ 'Dr. Westerlund'. This study contributes by analyzing the sensory experiences of _Pelargonium gravelens_ 'Dr. Westerlund' by using a trained sensory panel, resulting in a sensory profile. Such a profile, to our knowledge, has not been published elsewhere. The presented sensory profile may function as an important tool, not only in a health-related context, but it may also be highly important for horticultural stakeholders in developing consumer-oriented descriptive terms when communicating plants' unique odor compositions and how these are linked to health and well-being. This may also be of importance for the odor/scent industry in the development of new products, such as essential oils and hydrolates, for the support of human health and well-being.
