England is not a big country: from north to south and from east to west it is only about three hundred miles across. But for a small country[20]it has a surprisingly wide range of climates. People who have never visited England or who have visited only part of it often make the mistake that it is a very cold and wet country. Except for the summer months of June to September, this is probably true of the north of England and the Midlands. In the south, however, the climate is much more pleasant. One result is that when people retire from their work in the north, they often prefer to move down to the south.
    Perhaps the warmest part of the country is the southwest, which consists of the counties of Devon and Cornwall, where palm trees, bamboo and many semitropical plants grow well.[21]Flowers and vegetables ripen as much as a month earlier than those elsewhere. Farmers in the areas gain a higher price for their vegetables and flowers because they are ready earlier. In winter there may be several feet of snow in other parts of England but there will probably be no snow at all in the southwest. This may be one of the reasons why the southwest is one of England’s most popular holiday areas.
