Design Element 3--Light

 

    In garden design,
    light is direct, filtered, or reflected sunlight. The angle of
    the sun can have a dramatic effect upon color, both because the
    color of sunlight is reddened when it makes a longer pass through
    the atmosphere, and because the pupils of the eye under lower
    light conditions change the color signals to the brain. Often
    early morning and late evening colors appear more luminous than
    those with direct midday sun. Screens of trees with openings
    to this low-angle light can briefly transform the aura of your
    garden.

    

 

    


    Contrasting areas of light and dark intensify
    the experience of both. Here the path leads visitors from a sunlit
    stopping point to a heavily shaded tunnel under largeleaf rhododendrons,
    oaks, and pines. Different rhododendrons like varying amounts
    of shade, so you have ample flexibility to use rhododendrons
    in a variety of light conditions.

 

    
Effective use of shadow can continually
    change a particular scene throughout the day and the year. Shadow
    can highlight the unique trunk and branching structure of large
    rhododendrons. It can visually link the understory of shrubs
    with surrounding trees. It can accent the contours of your garden.
    Light and shadow can intensify or subdue color in both flowers
    and leaves, adding to the complexity and interest of a particular
    view.

    
Most of the trees here are pruned of all
    branches from five to ten feet above the rhododendrons around
    them. Light comes under the branches, while the trunks and tops
    create bold silhouettes. One of the most interesting for shadow
    patterns is the honey locust, a large but delicate tree with
    fine leaves and extensive branching.
