Taxodiaceae (sometimes Cupressaceae)
Dawn Redwood was known only from the fossil record until the 1940s when a botanist discovered extant specimens in a remote valley in China. Since then this deciduous conifer, a close relative of Taxodium distichum, has become a popular landscape tree in mesic temperate zone landscapes throughout the world. It has a broadly pyramidal outline, retains lower limbs and develops a fluted trunk around them with shaggy bark, and has slightly larger needles than Baldcypress which then turn a russet color in fall. This tree is a rapid grower, but it is drought intolerant.
