Formal landscaping is created with symmetry, clean lines, and closely-clipped plants. This style features lots of lush green where textures play off each other.
Though this style incorporates less lively color, formal doesn't have to mean a plain jane landscape. You can use handsome palms that have a symmetrical shape, subtle colors, a focal point like a fountain, tree, or arbor - even a specimen plant with a softer effect.
And formal can vary by degrees - a basic neatness and balance might be the elegant touch your landscape needs.
