As with American arborvitae (Thuja occidentalis), many varieties are cultivated ranging from extreme dwarf forms 2 to 3 feet tall to very fancy shapes and colors. The flat leaf sprays are disposed in vertical planes. When ripening, the cones may exhibit a luminous blue bloom that attracts attention; when crushed, they have a pleasant fragrance.

There are many old neglected specimens on campus, for example between Museum Way and Campus Drive. These are mostly stunted, presumably because of the lack of summer water, but they clearly possess ability to survive. Six more recent specimens flank three sets of steps leading up to the Main Quad from Serra Mall. Five of them are variegated in color; the sixth is different.
