An evergreen tree is a Christmas tradition in many American homes. The tree is usually a pine or fir（冷杉） 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 popular evergreen this time of year is the mistletoe（槲寄生） plant. It has small white berries and leaves that feel like leather. The traditional Christmas mistletoe is native to Europe. Ancient Druids believed mistletoe had magical powers. Mistletoe is a parasitic（寄生的） plant. It connects itself to a tree and steals nutrients and water.

And the poinsettia（一品红）is also one of the plants that many people connect with Christmas. Poinsettias __________ 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.
