The Bald cypress tree is the classic tree of southern swamps. There, in its native habitat, it displays a peculiar habit of raising conical "knees" from its roots. The function of these growths is something of a mystery, although some believe it is a way to help the roots get oxygen. This tree dwells in swamps because it out-competes most other trees on such sites.

To the surprise of some people, the bald cypress does quite well when planted in the right soil in yards or along streets and is a beautiful specimen tree. It has been grown successfully in cities as far north as Milwaukee and on dry Texas hills.
