Comments: The White Cedar is native in swampy areas in the northern US. White Cedar tolerates wet soils
and will grow on sandy soil. The foliage turns to a greenish russet in winter, especially on cultivars with colored foliage. The
species and its upright cultivars work wonders as a screening or
definition tree, especially in areas too narrow to use pines, spruce
and fir.
