     An evergreen tree is a Christmas tradition in many American homes. The tree is usually a pine or fir

dressed with lights and other colorful decorations.

     Families might buy a cut tree or go to a tree farm and cut one down themselves. Some people bring a

live tree in a pot into their home for the holidays and then put it back outdoors. Some people rent a

Christmas tree. Companies might bring the same live tree to the same family year after year. Or the tree

might get planted in a park or someplace else where it could help the environment.

     There are some trees that can be reused year after year because they are made of plastic or metal. Or,

instead of a tree, some people have a small, sweet-smelling rosemary (迷迭香) plant, cut to look like a

little Christmas tree.

     Another plant that many people connect with Christmas is the poinsettia (一品红). Poinsettias are

native to Mexico. They can be white or pink, but most are bright red. They are named after the first

American ambassador to Mexico. Joel Poinsett liked them enough to send some back to the United

States. Babies or pets that chew on poinsettias might get sick. But experts say the plant is not as poisonous as some people think.

     Like millions of other houses, the home of America's first president is decorated for Christmas. George Washington's Mount Vernon Estate is in Virginia. Visitors can hear stories about what Christmas was like at Mount Vernon in the eighteenth century. The museum where visitors begin their tour is decorated with

Christmas trees.
