Some of Oudolf's favorite perennials include Amsonia hubrichtii (Perennial Plant of the Year for 2011), Stachys 'Hummelo', Sedum 'Sunkissed', Sedum 'Matrona', Rodgersia 'Die Anmutige' and Aruncus 'Horatio'.
Oudolf himself has discovered and cultivated new varieties of perennials, including Echinacea 'Vintage Wine', Echinacea 'Virgin' and Salvia 'Eveline'.
Oudolf planting plans are works of art in themselves. His plans are extremely detailed, with repeating motifs of heights, color and foliage that vary in scale and create a rhythm.
Use these perennials in your garden - if you have the right conditions, of course - and the only other things you'll need are a few shrubs and trees and some ornamental grasses.
"As the famous Dutch gardener Henk Gerritsen remarked in regard to Oudolf's work: "The plants look wild. The gardens do not.""
