One of the most rewarding things I experience as a landscape designer is the element of surprise brought on by the growth and change of plants. I always visualize what a garden is going to look like while I am designing it, and most of the time the end result matches my vision. Sunlight, however, is one variable that significantly impacts the end result yet is not entirely in my control. Sunlight brings life to gardens in many ways beyond photosynthesis. The way that certain tree silhouettes drape themselves across patios, or grass shadows dance across a wall can be mesmerizing.
