Best grown in deep, moist but well-drained, acidic loams in full sun. Drought tolerant once established. Intolerant of poorly drained wet soils. Site trees in locations protected from wind. Habit and height can be controlled by how the central leader is trained. If supported, the central leader will slowly (one foot per year) grow upward. If unsupported, the central leader will cascade downward. Central leaders can be supported to a predetermined height (as 10’) and then allowed to cascade.
Cedrus atlantica, commonly called atlas cedar, is an evergreen conifer that is native to the Atlas Mountains in northern Africa (Morocco and Algeria). It is one of the true cedars. It basically grows over time to 40-60’ (infrequently to 120’) tall. Growing habit is usually loose pyramidal when young, becoming more flat-topped with long spreading branches with age. ‘Glauca Pendula’ is a columnar, weeping form featuring pendulous branches clad with bluish-green needles in clusters and upright, barrel-shaped cones. Training determines the form of the tree which can range from narrow-upright (if supported) to cascading in a variety of directions (if unsupported). Correct nomenclature for this cultivar is somewhat confused. Needles of Cedrus atlantica range in color, both in the wild and in seedbeds, from dark green to silvery-blue. Glauca Group attempts to deal with needle color variety by lumping blue-needled plants into Glauca group, with cultivar names being retained only for plants such as ‘Glauca Pendula’ which have uniquely different form. However, ‘Glauca Pendula’ is currently being sold by nurseries under several different names than the one used herein, including Cedrus libani ‘Glauca Pendula’ and Cedrus libani subsp. atlantica ‘Glauca Pendula’.
No serious insect or disease problems. Tip blight may occur. Heavy snow in winter can break branches.
