If you’re not an expert on trees (and maybe even if you are) you might be confused about the difference between two trees both called Red Cedars. There is an Eastern Red Cedar and a Western Red Cedar, but can you identify each one individually? How does one tell them apart, and what are their differences? Let’s take a close look at the two types of trees to see all the ways in which they differ and can be discerned from one another. The Western Red Cedar or Pacific Red Cedar is an evergreen that belongs to the genus Thuja. It is technically not a true Cedar, that is a member of the genus Cedrus. …The Eastern Red Cedar, sometimes known as the Eastern Juniper, is actually a species of Juniper found along the eastern coast of North America into southeastern Canada and down to the Gulf of Mexico.
