Bald Cypress: The Iconic Swamp Tree with Unique Knees and Rot-Resistant Wood

Natural History

Bald cypress (Taxodium distichum) thrives in wet soils along rivers, swamps, and streams. It lives up to 600 years, developing a buttressed trunk, feathery foliage, and distinctive pneumatophores ("knees") that emerge from waterlogged roots.

Appearance and Growth

Young trees are pyramidal; mature specimens become flat-topped, reaching 100–150 feet. Needle-like leaves turn orange-brown in fall. Cones are round, green, maturing to woody brown.

Uses and Value

Old-growth heartwood is prized as "wood eternal"—rot-resistant, strong, used for boatbuilding, shingles, carvings, and outdoor furniture. Cross-sectioned knees become decorative clocks and wall art. The species supports highly productive wetland ecosystems.

Landscape Use

Popular ornamental for its feathery texture and fall color. Adaptable to drier, well-drained soils but needs hot summers for optimal growth and cone production. State tree of Louisiana.
