Aesthetics is usually known as the judgment or reflection on art and culture and studies new ways of seeing and understanding the world. It is closely related to the philosophy of art.

“A garden is a complex of aesthetic and plastic intentions; and the plant is, to a landscape artist, not only a plant - rare, unusual, ordinary or doomed to disappearance - but it is also a color, a shape, a volume or an arabesque in itself.” Roberto Burle Marx

I’m not sure if this is exactly what you’re looking for but I defined aesthetics what I kind of think it is, and found a quote that I thought was neat. He is saying that the plant can be all these things and he looks at the plant in the garden and how it can be one thing but can also be something completely opposite. Full of color and life and then doomed of disappearance.
