Habit:  herb

Description:  "Trailing or climbing perennial with branching underground stems, stems unbranched above ground, up to 3 m or more, glabrous or thinly pubescent.  Leaves sagittate or hastate, variable in size, to 5 x 3 cm, glabrous or sparsely pubescent, acute or obtuse, lateral lobes usually spreading and acute.  Flowers usually solitary, axillary, sometimes in pairs, rarely in 3-flowered cymes.  Outer sepals obovate to broadly oblong, c. 4 x 2.5 mm, obtuse, truncate or mucronulate.  Corolla white or pink, rarely blue, 15-25 mm.  Ovary glabrous" (Davis et al., 1984; pp. 213-214).

Habitat/ecology:  "Although the plant can be found in waste areas, it can also grow in all kinds of cultivated lands.  It prospers in dry or moderately moist soils and because of its deep root system can survive long periods of stress.  It is not normally a weed of wetlands.  It grows best on rich, fertile soils but persists on poor and gravelly soils as well"  (Holm et al., 1977; pp. 98-104).

"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.  Humid areas, with almost constant rainfall, short dry periods are possible (generally not longer than 1 month); somewhat dry areas where the drought may last 3-5 months, precipitations of 400-800 mm. are concentrated in winter.  Fully exposed to the sun, level areas or slopes facing north"  (Chileflora).

Propagation:  "The plant reproduces by seeds and by sending up new shoots from a deep and extensive underground root system.  The seeds will remain viable in the stomachs of some migrating birds for periods up to 144 hours" (Holm et al., 1977; pp. 98-104).

Native range:  Europe, Asia, northern Africa, Azores (GRIN).
