Erechtites

not marked as a favorite taxon Erechtites hieraciifolius (Linnaeus) Rafinesque ex A.P. de Candolle. Common name: Fireweed, American Burnweed. Phenology: Late Jul-Nov. Habitat: In disturbed soil in nearly all habitats except the extremely xeric, present in most parts of the modern (beat-up) landscape at least as seedlings, liable to turn up at the smallest disturbance (such as small tree-fall tip-up mounds or campfires, even in large natural areas), most abundant in areas extensively disturbed or scarified by timber-harvest, bulldozing, or severe fire. Distribution: NL (Newfoundland) west to SK, south to s. FL and e. TX; West Indies; tropical America.

Glossary (beta!)

Origin/Endemic status: Native

Other Comments: Perhaps the only other species in our area as adept at appearing (seemingly from nowhere) at small soil disturbances in forests are Phytolacca americana and the moss Atrichum angustatum (Bridel) Bruch & Schimper.

Horticultural Information

NCBG trait

Intro: Erect annual found in disturbed soil in nearly all habitats except extremely dry ones.

Stems: Stems grooved-striate, unbranched, smooth or hairy.

Leaves: Leaves alternate, upper leaves clasping and lower subsessile, lance-shaped to oblong, to 8 in. long, sharply toothed or irregularly lobed, hairy or smooth.

Inforescence:

Flowers: Composite flowers (heads) in clusters at ends of upper-axillary stalks and terminating stem, about 1/4 in. wide (1/3 in. tall), cylindrical with a swollen base, consisting of numerous, densely crowded, tiny, white or dull yellow disk florets. A tube composed of erect, narrow, green bracts surrounds the head, nearly concealing the florets.

Fruits: Fruit a brown seed with a tuft of bright white hairs.

Comments: Present in most parts of the modern landscape, at least as seedlings, and liable to turn up at the smallest disturbance. E. megalocarpus, with larger heads and achenes, is found in northern parts of our area, in brackish and saltwater marshes of NJ, and may occur farther south as well.

Height: to 8 ft.
