5300’, Canyon bottom here, flowering near what looks like Heterotheca. Scattered along the washes in the area.
Maybe hybridizes with other Brickellia spp., at least according to Utah Flora.
Var longifolia the only one in Utah, or so I’ve read. Narrower leaves than var multiflora, which is more of a Mojave gal.
Asteroideae / Eupatorieae
