devil's club can actually be cultivated at sea level and is a desirable ornamental plant, producing an impresive floral display in the spring. all my books on northwest native plant gardening include it. if anyone wants to retrieve some I'll be glad to take it, to supplement the alder, vine maple, salal, alaska cedar, willow, oregon grape, etc I already have. And no way am I telling which national parks I got them from. Maybe we need a gardening forum on cc.com, something we can ease into in a few years when the mox thread runs it's course.
