You can use lush shrubs to make your small outdoor space seem larger than it is. By effectively "hiding" parts of your yard you create a greater sense of space and movement. Plant shrubs that fill out to touch each other or move potted plants to create mini-hedges. Remember that your plants will grow – even your smaller, shorter plants will eventually grow into bigger plants. The large leaves of big tropical plants can help to change the scale of a small space to make it feel larger.
