Structural Gardening

As I was setting up this blog, I came across a short, sweet on-line gardening course called Managing Perennials. Noel Kingsbury is the tutor and the course is about Piet Oudolf’s design principles.
Oudolf is a prominent figure in the New Perennial movement, responsible for the design of a number of very well-known and popular garden spaces — The Battery and the High Line in New York among them. The key concept seems to be structure: it’s concerned not so much with particular plants as with the relationships among them; not so much about building toward a particularly glorious point in the year as balancing combinations of plants so that they provide variety and visual interest all the time.
Structuralism is aimed at understanding the way language generates meaning. Structural gardening would seem to turn the project on its head, asking something like how does gardening speak.
