It’s so lovely at Hidcote that you could visit every week and notice something new. In fact I know someone who once visited every month one year, so as to see the garden changing throughout the four seasons. She can give you the Latin and common names for most of the plants, describe where they used to stand in her last garden and where they are now planted in her new one.
As for me I just like to sniff the scented air, admire the colours and shapes and imagine myself wafting around the garden with a book under one arm and a craft bag hanging from the other. A bell to ring for an afternoon gin and tonic, cocktail or pot of tea would also be good.
