During the 1600s, King James I used the land where present-day Buckingham Palace (the northern part) is located to plant mulberry trees in hopes of getting all the silkworms that feed on the fruit. According to The Telegraph, there is still a street called Mulberry Walk to honor that time, but King James I's efforts to get silkworms from the mulberries fell short.
Today, part of Buckingham Palace stands in the place where these mulberry fields once were. The mulberries are still represented at the palace, because the grounds are now home to the National Collection of Mulberries, which features 38 different forms of the trees that are planted throughout Her Majesty's garden (as well as Kensington Palace and Marlborough House).
