The Bald cypress is quite a large tree, capable of reaching heights of up to one hundred and fifty meters. The trunk is generally buttressed and fluted near the base, especially in wetter areas. The tree has a pyramid-shaped crown during its younger years and as the tree grows older, it becomes flat-topped. While it grows in water, the shallow roots tend to rise up above the soil to form cone-shaped pneumatophores, called its 'knees'.
