Use GREEN in the garden to...
Set a mood. The color green has healing power and is understood to be the most restful and relaxing color for the human eye to view (Bourne Creative).
Unify planting beds. Did you know that green is considered a neutral color in the garden world? Your color theme may be bright red or hot pink, but whether there are blooms or not, the greens tie the entire composition into a cohesive whole.
Emphasize other colors. Greens act as a backdrop to other colors, so carefully consider how the shade of green you choose will make other colors pop in the garden.
Explore subtle hues. Greens come in many hues including yellow-greens to gray-greens to blue-greens. It's a fun challenge to make a "green garden" by mixing hues so each shade of green pops in it's own way. Bonus: Consider mixing large and small leaves to create strong texture too!
