The similar grass that I have seen that come back is probably sledge grass. They are hardy in our climate.
This probably will show you that it is not for our zone. The tag on the plants I picked up twice were at Home Depot and they said hardy to zone 7. PNW is saying zone 9. If it is zone 9 a warm place like a basement or laundry room would be warm enough to store through the winter.
