A deciduous, softwood tree (''Taxodium distichum'') native to the wetlands of southeastern United States. The bald cypress produces of durable, decay resistant wood. The soft, lightweight wood is reddish-brown with a straight grain. It is often used for outdoor construction, roofing, fencing, flooring, and boat building. Because bald cypress timber is easily worked, it has also been used as an interior finish wood. The peak lumbering period for bald cypress was from 1870-1915 (Bucher 1996). When the bald cypress grows in a watery area, it has aerial roots called knees. The knees, because of their interesting shapes, have been used as souvenirs, art objects, and bases for flower arrangements. | A deciduous, softwood tree (''Taxodium distichum'') native to the wetlands of southeastern United States.

Description
A deciduous, softwood tree (Taxodium distichum) native to the wetlands of southeastern United States. The bald cypress produces of durable, decay resistant wood. The soft, lightweight wood is reddish-brown with a straight grain. It is often used for outdoor construction, roofing, fencing, flooring, and boat building. Because bald cypress timber is easily worked, it has also been used as an interior finish wood. The peak lumbering period for bald cypress was from 1870-1915 (Bucher 1996). When the bald cypress grows in a watery area, it has aerial roots called knees. The knees, because of their interesting shapes, have been used as souvenirs, art objects, and bases for flower arrangements.
