Baldcypress is the state tree of Louisiana and is an icon of southern swamplands. So named because the trees are deciduous (unlike most conifers), and have the peculiar trait of dropping all their needle-like leaves each winter.

The trees also develop unique aerial roots that protrude above the ground (or water) and are especially seen on trees growing in swamps. These structures are known as knees, and are sometimes harvested on a small scale and sold for woodcarving purposes.

Although not technically a cypress in the strictest sense (Cupressus genus), Baldcypress is in the Cupressaceæ family, which includes many decay-resistant woods (including cedars), and the wood is a popular choice in exterior construction applications where decay resistance is needed.
