@jamelamoroso, several robustly leafy plants dangling at the edge of a “ravine” with an intermittent stream at the bottom. The falling of a mature tree, once rooted at the same edge, has allowed sunlight in, and the loose soil around the upended roots is soft ground, supporting over 20 seedlings that emerged directly below two of the dangling plants. Lovely!
Woods, predominately hardwood, with loose granitic rock, and areas of exposed sandy substrate. Associates at this particular site include Collinsonia canadensis, Actaea racemosa, Christmas fern, Partridge Berry.
This property has at least two other small populations of this species, along with abundant Clinopodium georgianum throughout.

If “Rocky wooded slope above water” was a song, Eurybia mirabilis would be the melodic chorus.
@jamelamoroso , this wooded slope has a little-used access track for vehicles. On this track I counted 40+ flowering stems. Surrounding trees included various oaks, hickories and pine. This is on Pee Dee NWR land. Given the terrain, I would not doubt that there is more of this species on nearby slopes.

@jamelamoroso, this is a new-to-me population, but is on the next street over from a vigorous population I found last year. This is roadside, at the bottom of a slope where a drainage ditch spread out wider and transitioned into a level area by a crossroad intersection. One side of the road is the wild edges of residential properties. The other side is undeveloped rocky mixed woods with mature trees, a small stream, and a most astounding selection of invasives. Walking about 20 yards up the road, I counted 55+ flowering stems until the shade and invasives took over. Invasives I saw were: Dioscorea polystachya, Microstegium vimineum, Eleagnus pungens, Hedera helix, Ligustrum lucidum, Firmiana simplex, Ligustrum sinense, Ilex cornuta, Non-native Wisteria, and Berberis bealei. Having said that, the Eurybia was vigorous and very floriferous, looking most healthy!

@jamelamoroso, this is a new population to me. Walked 1/10 of a mile on the roadside in a southerly direction, and this lat and long is that of the northernmost plant I saw. In that 1/10 mile, on the east roadside, I counted 41 flowering plants. I did not walk further north from my initial sighting, so more plants are a possibility there.

@jamelamoroso, a new-to-me roadside population. I counted 27 flowering/fruiting stems and 2 non-flowering. Grassy, low roadside with dense and impenetrable wooded edge. Associates include tons of Parthenium integrifolium, some Coreopsis major, Sisyrinchium angustifolium, Asclepias viridiflora, and Packera anonyma.

Utility right-of-way. Generally disturbed, clay soil. Interestingly, although plants were scattered, many were growing close to the larger look-alike Tripsacum dactyloides.
@jamelamoroso, I am a bit overwhelmed and do not know what to say. The crazy thing is that @ungberg challenged me to find this historical species, what, 2 years ago? I spent lots of time learning about it, looking at images, etc., because I really wanted to meet that challenge, but never imagined I actually would. The plant introduced itself to Bruce and I this morning, with initial confusion from the two of us. Bruce may have a count for you. If not, I’ll gladly go back.
Eric, man, I give you ALL the credit for this. Let me know when you have another challenge for me.
