Course Description

Discover the perennial planting secrets and planting maintenance schedules from the High Line garden designer Piet Oudolf.

This course reveals Piet Oudolf’s revolutionary plantings of The High Line, New York City’s famous landscaped railway line that cuts through the centre of the city. Throughout the course, you will experience unique top down drone footage of The High Line and The Battery Park, so you can see a bird’s eye view of the plantings and their context.

During the videos, you will walk along The High Line discussing and observing the plants, with Piet Oudolf himself who designed the planting, and Dr Noel Kingsbury his long term co-writer.

As part of the course, we also hear from Andi Pettis, the acclaimed Director of Horticulture for The High Line who reveals fascinating insights on how they continue to maintain and manage the planting as the site evolves.

Once you understand the evolution and maintenance of perennial plantings in a harsh city environment, Dr Noel Kingsbury takes you through a practical approach of how to plant and maintain this type of landscape design.

The second part of the course features the New York Battery Park designed by Oudolf as an earlier work, with Dr Noel Kingsbury and Gabriela Marin (Chief Horticulturalist), Director of Horticulture for The Battery.

Finally you will learn the real ‘how tos’ of achieving the types of designs that Piet Oudolf has successfully pioneered in sites like The High Line and The Battery. Dr Noel Kingsbury talks to Helen Picton from Old Court Nurseries near Malvern in the UK, to teach you the practical activity you'll need ot maintain your perennial planting design.

Piet Oudolf & Noel Kingsbury - Gardening

Piet Oudolf’s landscapes are as peopled as they are planted. Folks flock to them, whether it’s the High Line in New York, the meadows at Hauser & Wirth’s art gallery in Somerset, or the Olympic Park in Stratford, to name a few.

Alys Fowler, The Guardian
"Structure is the most important component in a successful planting; colour is important too but it is a secondary consideration"

I looked at landscape gardening as a career alternative to my family business of catering. I'm probably best known as the landscape designer from the Netherlands! And I consider myself along with Noel Kingsbury as one of the leading figures of the ‘New Perennial’ or ‘New Wave Planting’ movement, using bold blocks of perennials and grasses to create Prairie style designs. My wife and I first opened a nursery in Hummelo, the Netherlands back in the 1980s, this is where my planting style emerged with strong block-type groupings based on structure and texture as much as colour. As my design style progressed I have focused on the perennial meadow, mimicking nature in my planting style. Nature is my biggest influence.

It comes as a surprise to some people that I'm also an early adopter of some technologies. I love using my iphone to capture videos and photos as I work. I have a large presence on instagram, and I'm excited to share my work through teaching on Learning with Experts. Dr Noel Kingsbury and I have been collaborators for over 25 years, and Noel will be with you in the classroom marking your work, while Noel and I developed and filmed the course materials together. We are planning more courses over time here too. I hope you enjoy your online courses with me.
