There is an innate human fascination with falling water. Waterfalls are a total sensory experience with sound, movement and color. They are doubly fascinating to those of us who were raised in the desert where water in any form, is at a premium. I may dream about living where water runs in the rivers and streams form waterfalls, but I always return to the desert. I guess I admire plants that can survive with little or no rain, more than those that have perpetual watering from the spray of a conveniently placed waterfall.
