A good garden design needs good bones.
Your garden has to look good even on a grey rainy day in Winter.
If you achieve this with structure such as flint walls, hedges, pergolas and paths then when Summer comes and everything explodes in lush greens and vivid colours the structure will support and frame the beauty that you have created.
Here are some images of structure in nature I have seen over the last month which no doubt is already informing me as I design.
Here is the great Montezuma pine at Sheffield Park, the skirt of new growth at the base of an ancient Sweet Chestnut, Rhododendron branches next to a lake, Halloween pumpkins still in a field, Yew topiary and the seeds of the wonderful Handkerchief tree.
