Omschrijving: Deze mooie decoratieve sierboom is winterhard en groeit krachtig.
The firs are large, stately conifers with single trunks, whorled branches and very symmetrical cone shaped habits. Firs can be distinguished from other conifers by the combination of flat needles which are whitish beneath, and upright cones which stay on the tree and disintegrate after the seeds have been shed, leaving behind a single spikelike axis for a while. White fir has yellowish green first year branchlets, needles that are bluish green above, and rough, pale gray bark. The needles are about 2 in (5 cm) long with a pair of whitish bands on the underside. They appear to grow in two ranks on the branchlets, resulting in flattened sprays of foliage. The upright cones are cylindrical, about 5 in (13 cm) long and purplish green. White fir can get over 100 ft (30.5 m) tall and its conical spirelike crown becomes more columnar with age.
