Common name(s): [more details]

English: earring flower, hardy fuchsia

French: ti zanneau

Hawaiian: kulapepeiao

Habit:  shrub

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.  "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.

Propagation:  Seed, possibly spread by birds.

Native range:  Southern South America.

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.
