Plants are nature’s natural air conditioners. A thick covering of foliage will create a cool sanctuary that can be enjoyed in the heat of summer. Trees have been used for centuries to create shade and the famous tree lined roadsides of France are said to be a legacy of Napoleon, who planted them to create a favourable environment for his marching troops. One group of plants that is under-utilised for their shade casting properties are climbers. Fast growing climbers are an idea.
