My first experience of a ''big'' garden was Versailles as a teenager and whilst I was impressed, I didn't really like it. I felt stifled and strangely underwhelmed by the flatness of it all. As luck would have it I then saw Hampton Court and it was official: I was off big gardens. It would be many years before I revised my opinion. On a trip to Harewood House it was too hot a day to be corralled into the house, so I wandered the gardens and found they were delightful. I felt uplifted. Then a cricket match at Stowe gave me the opportunity to walk the grounds for over an hour. I was completely won over and a devotee of Lancelot 'Capability' Brown. Sarah Rutherford's ''Landscape Gardens'' was an opportunity to put him in context.
