If you’re aiming for a sophisticated look, go monochrome. Choose one color palette—like various shades of pink—and plant different flowers that match that theme.

Think pink geraniums, petunias, and begonias. The uniform color will make your window box look chic and polished.

9. Trailing Ivy for a Lush, Green Look
