One of the most delightful things about England are its cottage gardens. Besides the wonderful big estates and gardens are small nondescript gardens which can be found even in crowded London. I found this in the Temple area of London, it was not small, it was quite sizable for London. But in London there are big garden parks. I took the bus to Hampstead Heath one morning which to my amazement was a huge wide and wild space. Regents' park is another huge garden space replete with formal gardens but the most amazing part is the Queen Mary rose garden containing 4,000 varieties of roses. If roses are your thing, the best time to see it is the first 2 weeks of June. The collection of old fashioned roses is found nowhere else in such abundance. You'll be so enthralled.
