An informal layout avoids straight lines, perfect symmetry, and tightly clipped hedges. Instead, it relies on sweeping curves, mixed borders, and plants allowed to grow into their natural shapes. Horticulturists use this approach to create a relaxed, organic feel that blends into the surrounding environment.
