A rare, semi-evergreen shrub, Baccharis dioica resembles the common groundsel bush, Baccharis halimifolia, but is quite distinct. In 1979, just before Hurricane Frederic did tremendous damage to the Mobile, Alabama area, we found this plant growing behind the dunes on Dauphin Island.
Baccharis halimifolia is a plant of edges and thresholds, growing where the land loosens and blurs into water: salt marsh margins, ditches, tidal creeks, and back dunes. In fall, when most things are shutting down, the groundsel bush erupts into a soft storm of white seed fluff, like a marsh firework frozen mid-explosion. This is the shrub that coastal Louisiana calls manglier, that botanists call groundsel bush or eastern baccharis, and that local healers have quietly trusted for generations.
