Native or not native plant with huge leaves at rest area on east side after Snoqualmie Pass on I-90 .
An Asteraceae that I know from a glance! Cacaliopsis nardosmia or silvercrown. It is a red-listed species in British Columbia, but common enough around the Wenatchee area of Washington. That's a nice patch for photographing it, my attempts so far have been in forest edge situations where it is crowded with other plants.
