Landscaping: Formal geometric design
Landscaping may be done keeping formal geometric forms in mind. The lines and forms of design maintaining a reference. The landscape and elements could be in the form of square or rectangle. In formal garden design, content becomes subservient to form. That is, nature supplies the plants (the content), but we apply such rigid guidelines in their arrangement (the form) that most of the attention is drawn to the form. Our own handiwork becomes the star of the show, while the plants play merely supporting roles. The plants chosen to support such a composition traditionally have been predictably the ones that are easiest to work with.
In formal gardens a series of carefully arranged and maintained boxwood hedges can be the whole garden: it is not a style much given to variety, nor do flowers assume a central role.
Greek people leaved in a world of perfection, beauty, geometry. So the formal geometric design was most popular among them. Armed with an orderly mindset disciplined by mathematics and in love with geometric patterns, we can even sometimes impose our will upon nature, which is a central theme in Western history, including formal garden design history.
