Also known as pine straw, long-leaf pine needles work best around acid-loving trees, shrubs, and perennials, such as Japanese maples, witch hazel, and delphiniums. The reddish-brown strands look especially natural on wooded properties. To get the most coverage, gently fluff the straw during application.
