Foliage Color

Foliage Color – In general people think of leaves as being green, but look again. Leaves can be all the colors of the rainbow. In itself, green is paramount in the garden. It is the color  that induces calm and tranquillity. It has the ability to  heighten pale colors and to tone down bright ones, and a  pleasant garden can he created with no other color but green. Gardens created entirely with foliage do have a  particular quality of unity and peace but they need not be only green.

Foliage comprises many other colors besides green, for example blues, silvery-greys, yellows, reds and cream and green variegations. Of course, these plants often have colorful flowers as well.
