I am Professor of Planting Design and Urban Horticulture in the Department of Landscape at the University of Sheffield. I’m a  plantsman, designer and pioneer of the new ecological approach to planting gardens and public spaces. My work revolves around the integration of ecology and horticulture to achieve low-input but high-impact landscapes that are dynamic, diverse, and tuned to nature. My work is based on decades of detailed experimental work, and widespread application in practice: I work as a designer and consultant and regularly collaborate with a wide range of other professions.  My work has been widely applied in the UK and abroad. In 2016 I was appointed as an Ambassador for the Royal Horticultural Society to spearhead their ‘Greening Grey Britain’ campaign, and I’m a former Garden Club of America International Fellow. I’ve has authored and co-authored key books on water-sensitive design, SuDS, and urban rainwater management (Rain Gardens: sustainable management of rainwater in the designed Landscape (Timber Press 2007), Green Roofs (Planting Green Roofs and Living Walls (Timber Press 2003)), and Urban Landscape Planting (The Dynamic Landscape: design, ecology and management of urban naturalistic planting (Taylor & Francis 2004). I’m a regular lecturer to audiences throughout the world.
