Over the years, myriad styles have been used to decorate the tree that annually graces the Blue Room of the White House, the official White House Christmas tree. Historians aren't exactly clear when the first tree was put up in the White House; it may have been either sometime in the 1850s or more like 1889.

But what we do know is that in 1929, then first lady Lou Henry Hoover began a tradition whereby the first lady would be in charge of decorating the annual tree. In 1961, Jacqueline Kennedy took things up a notch by choosing a theme for the White House Christmas tree. Both of those traditions live on to this day.

From the reign of the Kennedys to the era of the Obamas, the Blue Room tree has seen everything from patchwork quilted ornaments to crystal garland. Here's a look at the trees through the years.

1961, Jacqueline Kennedy
