Window boxes are a traditional and sure fire way to add great curb appeal to the exterior of your home. Fill these long rectangular planters with cascading vines, colorful flowers or attention-grabbing combinations to create a visually pleasing element each time you open your front door. Window boxes are quite versatile these days and come in a number of shapes and sizes for adding that special touch to the exterior of your home. Attach these rectangular boxes to just beneath windows, railings around decks and balconies and fences for an attractive, classic look to your home. Window boxes also come in many styles that will simply rest on the ground on your front or back porch, on ledges, steps or anywhere to create a distinctive and beautiful border that is full of life. Try adding tall grasses and shrubs to these window planters if you are going to rest them on the ground and section off a certain outdoor area.
