It is a compact and slow-growing small tree or large shrub with a narrow conical habit. The leaves are flat, twisted sprays of scale-like rich green foliage and have a citrus or fruity fragrance. It is the perfect evergreen for small vertical spaces in the garden. Pruning of its side shoots when the plant is young may be necessary to maintain its narrow habit.

The foliage may turn yellowish-brown or greenish-brown from cold exposure.
It is tolerant of clay soil, air pollution, and black walnut. Pruning should be completed in the early spring before the new growth appears.
