Garden by Piet Oudolf with a simple color palette, a cacophony of plant choices.
The Landform garden was designed by Catherine MacDonald and sponsored and built by Landform Consultants. It won Gold and Best Summer Garden and it wasn’t difficult to see why. The planting in this garden – rich and warm and perfectly in tune with the steel pergola and grey boundary fences. http://blog.lisacoxdesigns.co.uk/tag/coastal-drift-garden-2012/
