The only area in the entire eastern USA that Sunset recommends this tree for is the warmer parts of Sunset zone 32, but all other sources claim cold hardiness to USDA zone 7 (except AHS, but so many of their species hardiness ratings are outliers that I've learned to mostly ignore them at this point; I suspect they are more valid in the West).
In its natural range on the Pacific coast, includes the tallest living trees in the world; such habitat supplies most of the trees' moisture as fog. Does not grow as tall in the East, similar to the related Sequoiadendron, but NCSU still claims 3'/year on average.
"Fragrant flowers" here, of course, refers to the cones. Pollen may be allergenic.
Chlorotic in alkaline soils. Wind tolerance and pest susceptibility are debated. Protect from strong winter sun. Needs deep soil, preferably highly organic; tolerates heavy clay. USDA claims coppice potential and resprout ability, but since this is untrue of most conifers, I will not so tag without corroboration from another source.
'Adpressa'/'Prostrata' (though the American Conifer Society lists these as distinct cultivars) is a dwarf form that is hardier than the species, having survived -9°F in Raleigh. 'Cantab' is a reversion shoot of 'Prostrata' and is also the name that must be reassigned to any 'Prostrata' that reverts, throws a leader, and becomes upright instead of prostrate; logically it ought to have hardiness similar to that of 'Prostrata', but I cannot find it explicitly stated as such.
