24 key plants from Piet Oudolf's field at Hauser and Wirth art gallery and garden in Somerset

Although many see the installation as a garden, calling it a field is uncompromisingly faithful to its setting; the field stretches out like a huge, flat canvas that Piet has painted in great swoops of perennial plants, with no intervening trees or shrubs. In spring there are camassias and alliums, but the planting is designed to reach a thundering crescendo in summer, with rudbeckias and echinaceas, heleniums and sedums, actaeas and veronicastrums. Below is a list of the key plants Piet Oudolf has used in the design.

Colour is in the back of my head not on my tongue – I don't speak colour. Colour is so short. I look at the form of a flower and how it will last.
