The leaves, which have a pleasant scent when crushed, are in the form of small overlapping scales hugging branchlets arranged in flat sprays disposed more or less horizontally. Numerous horticultural varieties are available, including variegated, golden, and dwarf forms. The cones are about ½ inch long. The commercially important lumber is traded as northern white cedar. American arborvitae has been known as white cedar, a name that is also applied to incense cedar, Port Orford cedar, California juniper, and other trees.

Specimens planted in the 1890s in the arboretum apparently have been lost, but one venerable survivor is at the Bakewell Building, 355 Galvez Street, at the north end near three fine Taxus baccata ‘Stricta’. There is a specimen on the Campus Drive East side of Phi Kappa Psi. Another is to the right of the front steps to Phi Sig, 1018 Campus Drive (near the intersection with Mayfield).
