Piet Oudolf At Work offers an unprecedented look into the creative process of the renowned Dutch landscape designer, whose seasonal tapestries blur the line between wild and composed. This 276-page monograph (Phaidon, 2023), made in close collaboration with Oudolf, showcases his global gardens - from New York's High Line to Vitra's campus in Germany - alongside the largest published collection of his hand-drawn sketches and planting plans. Richly illustrated with full-color photography and essays by leading horticultural voices, the book reveals how Oudolf's New Perennial philosophy balances naturalistic beauty with ecological rigor.
