'Whipcord' is a compact, slow-growing conifer forming a flattened mound when young but gradually acquiring a more rounded shape, ultimately reaching a height and spread of 1.5m.

'Atrovirens' is a fast-growing, conical, evergreen conifer making a medium-sized tree with red-brown bark and aromatic, rich green foliage in spreading or drooping sprays
'Irish Gold' is a broadly conical evergreen conifer making a small tree with drooping sprays of rich green foliage heavily flecked and banded with yellow
'Stoneham Gold' is a slow-growing, compact, conical, evergreen conifer making a medium-sized shrub with dense sprays of bright golden-yellow foliage, tinged bronze in winter
T. plicata is a large, evergreen, narrowly-pyramidal tree reaching an ultimate height of up to 35m. Aromatic, glossy, scale-like, sharply-pointed leaves are held in large drooping sprays on spreading branches that curve upwards at the end. Cones are egg-shaped and around 1.3cm long
'Aurea' is a vigorous evergreen conifer making a medium-sized tree of conical habit, with spreading sprays of deep golden-yellow foliage
