A cedar tree has flat leaves that spray out into the shape of a fan, according to About.com. Small cones or pink flowers often are connected to the leaves.
A northern white cedar tree grows up to 50 feet tall and up to 4 feet wide, according to the Wilderness Classroom. The leaves of the northern white cedar tree are yellowish-green. The bark of a young tree is shiny and reddish-brown, while an older tree sports long strips of bark that turn darker with age. The bark spirals to the left as it grows for the first 100 years or so, then it changes the pattern and spirals to the right.
