If you are looking for inspiration for new landscaping ideas, or you happen to have a yard, consider growing your own vegetables. A vegetable gardens can look stunning, and there is nothing more beautiful than the unpretentious and the functional. Also, if you are going to water and maintain a yard, might as well get some healthy and delicious produce from it!
Try to incorporate principles of permaculture in your space. My favorites are; "Simplify", "Diversity", "Biological/unprocessed resources", and "Least effort for the most effect" These principles are good to apply in most facets of life!
