Enhance the charm of a cottage garden by incorporating handcrafted driftwood wall art. Use driftwood as a decorative element in a rustic garden gate or a garden arch. Plant cottage-style flowers like roses, daisies, and lavender. Add vintage-inspired garden furniture, birdhouses, and whimsical garden signs. This combination of driftwood and a cottage garden theme will create a romantic and nostalgic atmosphere, reminiscent of a quaint countryside cottage.
