A leading figure in the New Perennial planting movement, garden designer Piet Oudolf emphasizes plant structure as the most important aspect of a successful garden. Form and texture are valued as much as color, and perennials--prized for their beauty throughout a natural life cycle--are used almost exclusively. Oudolf challenges conventional approaches to gardening that rely on short-lived bursts of color and constant maintenance and shows the delights of working with versatile, expressive perennials to create lasting, ecologically sound panoramas that relate to the greater landscape and the shifting seasons.  This glorious full-color volume features twenty-three of Oudolf's most beautiful public and private gardens, including the widely acclaimed High Line and the Battery in New York City; the Lurie Garden in Millennium Park in Chicago; Wisley, the Royal Horticultural Society Garden in Surrey, England; the Pensthorpe Nature Reserve and Gardens in Norfolk, England; the Trentham Estate in Staffordshire, England; Il Gardino delle Vergini at the 2010 Venice Biennale; the Dream Park in Enkoping, Sweden; and his own perpetually evolving garden in Hummelo, The Netherlands.  Insightful, accessible text by gardening author Noël Kingsbury places Oudolf's work in context and explains how each garden and the plants selected for it fit the specific environment. Oudolf's detailed plans provide inspiration and insight for all interested in small personal gardens and the design of large-scale public landscapes alike.
