Create a serene coastal garden oasis by pairing shabby chic benches in pastel colors with floral cushions. Opt for benches with a distressed white or weathered wood finish, reminiscent of beachside cottages. Choose floral cushions in soothing pastel shades like seafoam green, sky blue, or sandy beige. Surround the benches with coastal plants like seagrass, succulents, and beach roses. Add nautical elements like driftwood accents, seashells, and a vintage ship wheel. This garden inspiration will evoke a sense of tranquility and the refreshing ambiance of a coastal retreat.
