Window boxes are the perfect way to make dormers look extra special. Create lots of season-long interest with a mix of profuse bloomers, such as this verbena, and unusual foliage, such as flowering kale and sedge. That way you can enjoy the beautiful leaves and their distinct textures if the flowers take a break.
