PYRAMIDAL ARBORVITAE. Named in 1865 Germany. A wholly inapplcable name, as is the 1867 'Stricta'. The 1892 'Columnaris' is best, but nurseries prefer the 1907 name 'Pyramidalis'. The dates just cited are the officially recognized dates of publication, and "Pyramidalis" was in commercial use <1907. In any case this clone 9or these clones, probably) is ubiquitous. Used for screens, hedges, and foundation plantings. Columnar or very narrowly pyramidal, with very short branches bearing moderately dense foliage and many cones. Brownish in winter. Gradually being replaced by cultivars greener in winter. Record: 43' x 5'10" x 12' Sedro Woolley, WA (1988).
