Terminology Full sun describes areas receiving six to eight hours
of direct sun daily.
Partial shade or partial sun is an interchangeable term
describing areas that receive three to six hours of daily sun.
A partial-sun plant usually relies on receiving minimum sun
requirements, while a partial-shade plant needs relief from
afternoon sun.
Full or dense shade describes areas receiving less than
three hours of sunlight per day. Located under thick trees or
evergreens, they receive little or no direct sun. Limited varieties
of ferns and flowers with evergreen leaves survive these conditions.
Adjustments may be necessary to increase sunlight and expand
plant choices.
Light shade conditions are prominent under high-canopy
trees and east and north building foundations. Plantings could
include shade-loving and shade-tolerant plants.
Dappled shade refers to areas where sun slices through
tree branches. Sun is permitted to penetrate small-leaf canopies,
such as those of Russian olive or locust trees, in a moving
pattern during the day. Shade- and sun-loving plants can thrive
in these beds.
The small leaves of this Russian
Olive tree allow dappled sunlight to penetrate its canopy.
