Pacific Northwest Gardening: Coltsfoot, 1 by bonehead

Just back from camping up at Klipchuck (east side of North Cascades) where there were lovely stands of what I believe to be coltsfoot (Petasites palmatus or perhaps frigidus). The seed heads were about ripe and I've borrowed a couple stalks, hoping to germinate them next spring. Has anyone had any experience with this plant? Per my research, it appears to be originally introduced from Japan but is now considered a PNW native. I'm hoping to plant it out in a damp spot in my wild zone and let it have its way. Thanks for any info.
