Thuja plicata
western redcedar, western arborvitae, giant arborvitae

Notes:

Not the same genus as eastern redcedar (Juniperus virginiana).

Generally stays green in winter, unlike many forms of T. occidentalis, and is also alleged to be more deer resistant than same.

Taprooted. Moist, cool climate preferred (native to Pacific Northwest). Clay and sand tolerance are debated (Missouri BG and Cal Poly vs. the USDA).

'Green Giant' (likely a hybrid) has earned the PHS Gold Medal Award. 'Atrovirens' is dense with slightly upswept branches; possible Leyland cypress substitute? 'Virescens' is very similar, tight but somewhat less graceful than the species. 'BFC68' (Virginian) is a sport of 'Green Giant' denser, more compact, and slower-growing.
