Portland, OR (NW Oregon in general) also has a lot of planted Giant Sequoias! So it may not be strictly true that they are super picky. I imagine as climate warms, the PNW will become a better spot for Sequoias. Unfortunately at the cost of trees that like it cooler and wetter e.g. Western Red Cedars.
I would plant one, but their trunks get huge quickly, and I see a lot of busted sidewalks around here due to that.
