"From Palm Tree to Cream Tea" explains quite a lot. It has been almost 6 months since I have left, and I have yet to see a single palm tree in England. Therefore, the image of the palm tree represents to me the sunny beach only 20 minutes from the home I left in California- not to mention the palm trees lining the city streets.
Having a "Cream tea" on the other hand, is one of the most English things I can think of (having only observed the country for about 9 months now). What a cream tea involves is drinking tea while eating a scone with clotted cream and jam.
Your challenge, if you are able, is to go find a palm tree, sit under it, and enjoy a cream tea. Best of both worlds.
