Declared one of the Seven Wonders of the Ancient World, the Hanging Gardens of Babylon, continue to inspire esthetes to this day, thousands of years after the very last flower in them perished. It is impossible to say if this was the first use of terraces and baskets for raising and displaying plants, but it is certainly the most famous one.
Of course gardening has made a lot of progress since the days of Babylon, yet some ideas have stood the test of time. Hanging baskets are surely one of them. In our days they are made of different materials, come in a lot more shapes and sizes, but have never stopped being a current trend.
Most gardeners would agree that some plants look better when observed from above, others from an upward angle. There are numerous options for positioning the first kind and not that many for the second. Actually short from placing a pot on high place, where it is pretty possible that it will fall and break, using a hanging basket is the only choice many people have.
