Description:  "Small shrubs;  stems long, arcuate, 1-2.5 (-4) m long.  Leaves in whorls of 3-4 per node or sometimes opposite, ovate to lanceolate, 2.5-6 cm long, 1-2 cm wide, margins serrate, petioles 0.5-1 cm long.  Flowers perfect, axillary and pendent, peduncles 3-4.5 cm long; floral tube magenta, 10-13 mm long; sepals magenta, 20-25 mm long; petals dark purple, convolute after anthesis, 10-13 mm long; stamens exserted; filaments 25-30 mm long.  Berries ellipsoid, 10-15 mm long"  (Wagner et al., 1999; pp. 996-997).

Habitat/ecology:  Ornamental plant; many cultivated fuchsias are hybrids of Fuchsia magellanica.  "Forest margins, scrub, woodland, riparian habitats.  A variable shrub with a number of varieties and cultivars.  It often forms dense thickets and scrambles over other shrubs and small trees.  Extensive stands develop in disturbed sites, impeding the growth and regeneration of native trees and shrubs"  (Weber, 2003; p. 176).

"Dense infestations in the La Reunion islands occur along paths and tracks, where the plant may form dense tangled thickets which shade out native understorey plants and alter the structure of the vegetation" (Csurhes and Edwards, 1998; p. 161).  Naturalized in mesic to wet forests up to 5000 ft. elevation in Hawai‘i.  "In Chile this species grows in the following environmental conditions:  Medium altitude up to the timber line; low altitude, interior valleys; coastal mountains, 500-2000 m; coastal areas, 0-500 m.  The plant grows in water or it has its roots within a permanent water course, this corresponds to marshes, bogs, water courses, lake and river shores; humid areas, with almost constant rainfall, short dry periods are possible (generally not longer than 1 month).  Some shadow, some protection against direct sunlight, some shadow from vegetation, filtering about 20-40% of light; in shadow, steep slopes facing south or a vegetation cover which filters 40-80% of light"  (Chileflora).

Propagation:  "Seeds are dispersed by birds and water"  (Weber, 2003; p. 176).

Native range:  Argentina and Chile; cultivated and naturalized elsewhere (GRIN).

Control: 

Physical:  Hand pull or dig out seedlings and young trees.

Chemical:  Cut plants and treat regrowth with a herbicide; larger plants can be cut and the stumps treated with herbicide (Weber, 2003; p. 176).
