Blue Atlas Cedar Cedrus atlantica ‘Glauca’ This is a popular specimen tree with glaucous greyish-blue foliage. In time it will attain 35m in height and a similar crown spread. Narrow needle like leaves are arranged in whorls around the stem. Now a young tree, but after a few years, it will produce barrel shaped cones which will sit upright on the branches.
