yes, they are native to and seem to prefer a relatively cool ("equable")maritime/oceanic climate----which is perhaps why they seem to grow best in coastal northern California and southern Oregon. you can see them growing in other places further south and inland but they often seem rather spindly and not as robust compared to those further north especially if planted in full sun and treated as "xerics" (which they are not). phormium/New Zealand flax comes from the same habitats and like similar cultivation conditions though is perhaps more tolerant of a bit more heat and drought.
