Any permies have more information? We have a couple of these growing in our garden. This year we're going to try some wild seed harvesting, and since these thing are bee/butterfly magnets, it's at the top of the list. They stick out beautifully among all the other wildflowers; they have a really distinct look. This is about the most in-depth information I could find. If anyone has permaculture-specific uses, please let me know!
This was a very good year for Joe Pye Weed in my area. I love them just cuz they're native and they're pretty insect magnets (as you say), but I've never used them for anything else. Couldn't find anything permaculture related.
