Establishment means:Sparingly established
Erect or ascending rhizomatous, colony-forming perennial herb to c. 2 m tall; stem striate, mostly unbranched, glabrous, gland-dotted, resinous. Leaves petiolate, lanceolate, 50–130 mm long, 8–30 mm wide, entire or denticulate, glabrous, black gland-dotted, acute to acuminate at apex. Capitula in dense, terminal corymbs; involucre hemispherical, those of male capitula 3.5–5 mm long, those of female capitula 3.8–4.8(–6) mm long; involucral bracts narrowly lanceolate, 2–4 mm long, glabrous, gland-dotted, resinous, inner series ± equal; margins erose or ciliate. Male florets 26–40; corollas 3.5–4 mm long (based on non-Australian plants). Female florets 80–150; corollas 1.7–3 mm long. Cypselas obovoid, sometimes curved, 0.6–1.5 mm long, light-brown, 5-nerved, glandular, hispidulous at apex (based on non-Australian plants); pappus 2.6–4(–7) mm long. Flowers spring–autumn.
*Gold. Native to the east coast of USA, Baja Peninsula and South America. Sparingly established in paddocks at a single location near Maryborough in central Victoria.
Baccharis glutinosa has been known in Victoria for over 20 years and in this time has not spread beyond its original location. This may be due to spread being entirely by rhizome given that only female plants have been observed at the site.
