Ornamental plants, valued for their varied morphological characteristics, are increasingly used in urban greening initiatives such as rooftop greening. But this application presents challenges like limited soil depth and no irrigation, requiring plants such as the Phedimus species, known for their resilience to these conditions. Current research focuses on understanding the genetic and seasonal morphological changes in these plants, with a particular interest in their variations in color and patterns of dormancy. However, there is a lack of progress in genetic and breeding research, and the methods for evaluating morphological traits are still in the early stages of development. While recent advancements in multispectral image analysis provide promising solutions for non-destructively evaluating plant traits, their application in assessing ornamental plants is still limited.
