"Large perennials; culms erect or arching, up to 8 m tall, unbranched or branched above, arising from thick, scaly rhizomes, nodes glabrous, usually concealed, internodes hollow, up to 4 cm in diameter.  Leaves strongly distichous, distributed rather uniformly along culm except on old stems; sheaths longer than internodes and strongly overlapping, glaucous, glabrous to sometimes sparsely long-villous at throat; ligule a thin, whitish or brownish, minutely ciliate membrane, 1-1.5 mm long; blades thick and coriaceous, 45-60 cm long, 4-6 cm wide, glabrous, glaucous, striate, margins scabrous, leaf bases broader than sheaths, with prominent, triangular, brownish flanges, ciliate along margins.  Inflorescences paniculate, ovoid, 40-70 cm long, plumose, dense, the branches stiffly ascending; spikelets densely clustered along secondary or tertiary branches, 13-17 mm long, 4-5 flowered, rachilla glabrous; glumes hyaline, brownish or purplish, 11-13 mm long, narrow, acuminate, scabrous on the indistinct keel; lemmas membranous, lanceolate-ovate, 8-15 mm long, tapering to a short straight awn arising between 2 delicate lateral teeth, 3-7-nerved, usually 3 major ones anastomosing with midnerve, lower portions on dorsal surface of lemma heavily bearded with long silky whitish hairs, the hairs 8-10 mm long; palea whitish, membranous, 5-10 mm long, ca 1/2 as long as lemma, scabrid on keels and pubescent near base between them, hyaline, truncate.  Caryopsis elongate, 1-1.5 mm long" (Wagner et al., 1999; pp. 1498-1499).

"Grande herbacée pérenne dressée, formant des touffes denses atteignant 2 à 8 m de hauteur, reconnaissable à son allure de canne ou de bambou, à ses tiges de 1 à 4 cm de diamètre portant des feuilles de couleur vert-pâle avec de grands lobes basaux et à sa grande inflorescence (30 à 60 cm de long) dressée de couleur crème à brune" (Meyer, 2008; p. 31). In moist areas, such as along ditches and riverbanks.  "Once established, giant reed can form huge clones, sometimes covering hundreds of acres.  It is highly flammable and resprouts quickly after burning.  Fires help transform communities of native plants into solid stands of giant reed, changing riverbank forests from flood- to fire-defined habitats" (Randall, et al., 1996).

In Hawai‘i, "naturalized in coastal areas, often in thickets" (Wagner et al., 1999; pp. 1498-1499).  In Fiji, widespread on hillsides, in open forest, and along roadsides, up to about 200 m (Smith, 1979; pp. 299-300). In New Caledonia, "parfois planté, notamment pour stabiliser les talus des routes. Largement répandu à l'état spontané" (MacKee, 1994; p. 56).  "In Chile this species grows in the following environmental conditions:  Low altitude, interior valleys; coastal mountains, 500-2000 m; coastal areas, 0-500 m.  Humid areas, with almost constant rainfall, short dry periods are possible (generally not longer than 1 month).  Fully exposed to the sun, level areas or slopes facing north"  (Chileflora). Rhizomes; fragments of stems, often carried by water. Tropical Asia and the Mediterranean region, now widely naturalized in warm temperate to tropical areas.

An ornamental variety, A. donax var. versicolor (Mill.) Stokes is widely cultivated. It has white-striped leaves.

Reported to be under cultivation in Fiji.

An invasive species in riparian areas in California (US). Additional control information from the Bugwood Wiki.

Physical:  "Cut down close to ground. Dig out entire root/rhizome mass. Dispose of at refuse transfer station or by burning. While slashed stems can be left or dumped, stumps always resprout and digging root masses can leave rhizomes behind"  (Weedbusters New Zealand).

"La lutte manuelle par arrachage des plants est difficile en raison de la capacité de multiplication végétative de l’espèce" (Meyer, 2008; p. 31).

Chemical: "Herbicides must be used to ensure that the root mass is killed because even tiny fragments of rhizome can grow into new colonies.  Both glyphosate and fluazipop herbicides have proven effective, especially when applied after flowering.  Because this species tends to spread downstream, it's important to remove infestations from the upper reaches of a watershed first"  (Bell, 1996).  "Cut down close to ground. Spray regrowth with Amitrole (10ml/L) + Gallant (10ml/L) + penetrant before it reaches 60 cm. Continue respraying at under 60 cm until regrowth ceases (normally requires 4-6 treatments). Minimise herbicide contact with soil and other vegetation as Amitrole is non-selective, residual and corrosive. Stray emergent shoots can be cut at ground level and 10 ml undiluted Amitrole injected into each stem"  (Weedbusters New Zealand).

"La lutte chimique par application d’herbicide sur les racines (avec du glyphosate ou du paraquat) est délicate en raison de la proximité du lac de cratère" (Meyer, 2008; p. 31).
