I expect they were grown along the southern Oregon coast, where Lilium 
longiflorum (Easter lily) is also a major crop. It is much warmer there in 
winter. Cutflower producers also grow a lot of them in poly hoop houses.

Presumably they lift them, as they do most everything, store them in 
climate-controlled warehouses, and plant them late in fall or in winter so 
that they don't make top growth and freeze out.

That said, Dutch irises do get through the warmer winters here, such as the 
past two or three.
