The dutch designer Piet Oudolf aims for ‘a complicated layering of seasonality, energy, endurance and reward — both before, during and after flowering’, in his gardens. One of the leading figures in the New Perennial movement, Oudolf’s gardens achieve a rare stability in a pared-down palette. One notable work is his own Oudolf Hummelo, in the Netherlands, a ‘dream landscape’ where herbaceous perennials are both contained and permitted to flourish within a set of structures. As Oudolf has told The English Garden: ‘A garden is exciting for me when it looks good through the year, not just at one particular time. I want to go outside and for it to be interesting in all weather.’ He also designed the garden at the Hauser & Wirth Gallery in Bruton, Somerset.
