Piet Oudorf “New perennial” movement.

Considered the most influential garden designer of the past 25 years,” Dutch plantsman Piet Oudolf has popularized the “New Perennial” movement.  Oudolf’s approach to planting extends beyond the technical to concepts of composition, time and temporality, repetition, and contrast. His goal is to create “dream landscapes”  — his designs and plant compositions using bold drifts of herbaceous perennials and grasses which are chosen at least as much for their structure as for their flower colour.
