Baldcypress is a long-lived, deciduous wetland species that grows along rivers, streams, and creeks as well as in swamps with slow moving water. It can live up to 600 years old. It is a legendary tree of the Deep South known for its "knees," moss-draped crown, and buttressed trunk. It occurs in the coastal plains along the Gulf and the Atlantic Ocean and north up through the Mississippi River Valley. Because of the unique shape of the base of each trunk, artists
have created clocks, furniture, and wall décor from the
cross-sections of this tree. In the landscaping industry, baldcypress
is planted for its ornamental beauty. Old-growth heartwood is
especially desired in the timber industry for its durability
and resistance to rot. However, lumber use has declined because
it is a slow-growing tree, it is harvested from wetlands, and
the population of mature trees is much smaller than in the past. |

swampland ecosystem. It is valuable for wildlife food and cover. Canadian geese migrating to the south feed on the seeds. Swamp rabbits and other birds, such as Florida cranes and ducks, also feed on baldcypress. White-tailed deer escape to the cover of baldcypress swamps during hunting season. Many animals find shelter in and around the base of large old-growth trees. Old-growth baldcypress has a flattened crown usually dangling with Spanish moss (Tillandsia usneoides). Some river edges still have stumps of giant cypress trees that were logged in the early 1900s. A few old giants live in parks across Florida. Baldcypress and pondcypress are in the Taxodiaceae family, which are not true cypresses. True cypresses are in the Cupressus family and are not native to the southeastern United States. Baldcypress can be easily confused with another variety of the same species, pondcypress (Taxodium distichum var. nutans). Close attention to detail can differentiate these two varieties. Pondcypress has smaller, scale-like leaves pressed on the twigs. A twig of pressed pondcypress leaves resembles a pine needle pointing up or out from the branchlet. Baldcypress leaves are linear and featherlike, and the twigs hang down looking more pendulous than pondcypress twigs and leaves. Also, pondcypress tends to occur in still-water wetlands rather than flowing-water wetlands of the baldcypress habitat. "Knees" are present in both pondcypress and baldcypress root systems when they are growing in water. Cypress "knees," or pneumatophores, are cone-shaped extensions of the root system protruding from the ground. Pneumatophores are thought to function as the trees' means of obtaining oxygen for the roots during flooded conditions. Baldcypress and pondcypress are "Trees with knees." |

| Identifying Characteristics | ||
Size/Form: |
Baldcypress is a large tree which may reach heights of 100' to 150'. The trunk is usually buttressed and fluted at the base in extremely wet areas. It has a pyramidal-shaped crown when it is young that gradually becomes flat-topped with age. When growing in water, it has shallow roots that often arise from the soil in the shape of cones called pneumatophores, or "knees." | |
Leaves: |
The leaves are deciduous, linear, and spreading 2-ranked like a feather. Each leaf is ½" to ¾" long. The flat needle-like leaves are light yellow-green. | |
Fruit: |
The fruit is a round cone that is about ¾" to 1" in diameter. They are wrinkled, green, and leathery. Upon maturity the cones become woody. The shield-shaped scales fit closely together before the cone disintegrates. | |
Bark: |
The reddish brown to ashy gray bark is thin and peels in narrow vertical strips. | |
Habitat: |
Baldcypress grows in slow and fast flowing-water wetlands. Other species associated with it include red maple, slash pine, swamp tupelo, sweetgum, bluff oak, and swamp chestnut oak. | |
