I knew the plant as Dollar weed. It is beautiful in floral arrangements, but is becoming rare due to over harvesting. I don't believe you're supposed to take anything out of a National Park. Be careful, please.

I would check with the forestry service.
I'm sorry. I don't know either so definitely check with the Park Service
It is getting scarce due to overharvesting
I'm sorry I don't know what galax is
