Taxodium distichum
A flood-tolerant deciduous conifer with rot-resistant heartwood.
Taxodium distichum, commonly known as bald cypress, swamp cypress, or red cypress, is a deciduous conifer in the family Cupressaceae native to the Southeastern United States. It is noted for its russet-red fall color, extreme flood tolerance, and rot-resistant heartwood, making it valuable for timber and widely planted in public spaces. This hardy, adaptable tree thrives in a broad range of soil conditions, from wet and swampy to dry, salty, or alkaline environments, and can tolerate atmospheric pollution. It grows best in full sunlight to partial shade. The tree produces needle-like leaves that turn yellow or copper red in autumn before falling. As a monoecious species, it bears male and female cones on the same plant, with pollination occurring in early winter and cones maturing in about twelve months. The female cones are globular, composed of 20 to 30 scales, each holding one to three triangular seeds; each cone contains 20 to 40 large seeds, the largest of any Cupressaceae species. Cones disintegrate at maturity, releasing seeds that are produced annually, with heavy crops every three to five years. The tree’s heartwood is highly rot-resistant, making mature trees prized for fence posts, doors, flooring, and caskets. The tallest known specimen stands 44.11 meters tall near Williamsburg, Virginia, while the National Champion, located in Louisiana’s Cat Island National Wildlife Refuge, is estimated at 1,500 years old. The oldest known living specimen, found along North Carolina’s Black River, is at least 2,624 years old, making it the oldest living tree in eastern North America. The species was designated the official state tree of Louisiana in 1963.

Lore & Background
Taxodium distichum is a large, slow to fast-growing, and long-lived deciduous conifer. It typically reaches heights of 35 to 120 feet with a trunk diameter of 3 to 7 feet. The main trunk is often surrounded by distinctive cypress knees. Its bark is grayish brown to reddish brown, thin, fibrous, and stringy in texture, with younger trees having more easily peelable bark. The needle-like leaves are simple, alternate, green, and linear, measuring 1/2 to 3/4 inch long with entire margins. In autumn, the foliage turns yellow or copper red before falling. The tree is monoecious, bearing both male and female cones on the same plant. Male cones emerge on slender, tassel-like panicles 4 to 5 inches long, while female cones are round, resinous, and green when young, becoming hard and brown at maturity. Each globular female cone, 2.0 to 3.5 cm in diameter, contains 20 to 30 spirally arranged, four-sided scales, each bearing one to three triangular seeds, yielding 20 to 40 large seeds per cone—the largest seeds of any Cupressaceae species. Cones disintegrate at maturity to release seeds, which are produced annually, with heavy crops every 3 to 5 years. Seedlings typically have six cotyledons. The species is highly adaptable, thriving in full sunlight to partial shade and tolerating wet, dry, salty, or swampy soils, as well as acid, neutral, alkaline, and saline conditions. It is extremely flood tolerant and moderately drought hardy, and can withstand atmospheric pollution. Its rot-resistant heartwood is valued for fence posts, doors, flooring, and caskets. The native range extends from southeastern New Jersey south to Florida, west to Central Texas and southeastern Oklahoma, and inland up the Mississippi River to southernmost Illinois and Indiana. Notable old-growth stands exist at Corkscrew Swamp Sanctuary in Florida and along North Carolina's Black River, where trees have been dated to over 2,600 years old, making it the oldest living tree in eastern North America. The tallest known specimen, near Williamsburg, Virginia, reaches 145 feet, while the National Champion, in Louisiana's Cat Island National Wildlife Refuge, stands 96 feet tall with a 56-foot circumference and an estimated age of 1,500 years.
Reader's Guide
The bald cypress is a deciduous conifer native to the Southeastern United States, noted for its remarkable adaptability to diverse soil conditions, including wet, salty, dry, and swampy environments, as well as its tolerance of atmospheric pollution. Its russet-red autumn foliage and lacy needles provide ornamental value, leading to its frequent use in groupings within public spaces. Ecologically, the tree is both extremely flood tolerant and rather drought hardy, and its cones are commonly consumed by wildlife. The species is monoecious, producing male and female cones on the same plant, with seeds ripening in October; the seeds are the largest of any species in the Cupressaceae family. The tree’s rot-resistant heartwood, which develops at maturity, is highly valued for practical applications such as fence posts, doors, flooring, and caskets. Historically, the bald cypress was designated the official state tree of Louisiana in 1963. Notable specimens include the National Champion Bald Cypress in Cat Island National Wildlife Refuge near St. Francisville, Louisiana, estimated to be approximately 1,500 years old, and the oldest known living specimen, found along the Black River in North Carolina, which is at least 2,624 years old, making it the oldest living tree in eastern North America. The Senator, a bald cypress in Longwood, Florida, was estimated to be 3,500 years old before it was accidentally burned down in 2012. The species’ native range extends from southeastern New Jersey to Florida and west to Central Texas and southeastern Oklahoma, and inland up the Mississippi River to southernmost Illinois and Indiana. Ancient forests, with trees over 1,700 years old, once dominated southeastern swamps, and the largest remaining old-growth stands are at Corkscrew Swamp Sanctuary in Florida and along North Carolina’s Black River.
Frequently Asked Questions
Who is Taxodium distichum?
Taxodium distichum is a deciduous conifer in the cypress family (Cupressaceae) that grows natively across the flat, wet lowlands of the American Southeast. Fans often call it bald cypress, swamp cypress, or red cypress, and it stands out as one of the very few conifers that sheds all its needles every winter.
What are Taxodium distichum's powers/role?
Its standout ability is tolerating months of standing water without dying, a trait almost unheard of among conifers. It also produces heartwood that resists decay remarkably well, making it a long-standing favorite for outdoor construction, boat-building, and fence posts.
Where does Taxodium distichum call home?
Its native stretch runs from New Jersey down through Florida and westward into Texas and Oklahoma, following the Mississippi River valley and its tributaries. It thrives in slow-moving rivers, oxbow lakes, and bottomland swamps where the water table stays high year-round.
Why is Taxodium distichum important to the canon?
Beyond serving as a keystone species in wetland habitats, its durable, rot-resistant timber has made it a go-to material for docks, outdoor structures, and furniture for generations. It is also one of the most widely planted shade and ornamental trees in parks and streetscapes across the country.
