Description:  "Deciduous herb; rhiz thick, ascending. Lf peti 6-18" long, hairy; blades peltate, broadly ovate to nearly circular, to 18" long, 12" wide, both sides green, base rounded, symmetrical, margins finely serrate, ciliate, apex shortly pointed. Infl of forking, cymose clusters, stalk taller than lvs. Flws white or pink-tinged, to 0.5" ⌀. . . . The lily-pad or lotus begonia [Begonia nelumbiifolia] has large, peltate leaves like those of its namesake water plants." (A Tropical Garden Flora, p. 177)

"Herbaceous; rhizome repent, short, 15 mm. thick, setose, internodes extremely short; stipules persistent, lanceolate, over 2 cm. long, entire, rather firm, pilose; petioles 15-45 cm. long, 8 mm. thick, parsely rufous-hirsute, soon glabrous; leafblades peltate, obliquely very broadly ovate or subelliptic, 7-9-nerved, evenly rounded except for the abruptly acuminate apex or slightly produced at the ends of the nerves, remotely denticulate, soon glabrous, the margin ciliate and sometimes purple, 17-40 cm. long, 10-28 cm. wide, thin; peduncle usually exceeding the leaves, to 66 cm. long, 6 mm. thick, soon glabrous; cymes regular, much branched, diffuse, 2-5 dm. broad; bracts deciduous, ovate, obtuse; pedicels slender, 9-22 mm. long; staminate tepals 2, suborbicular, 6-8 mm. long, white or pale pink; stamens few, anthers narrowly obovate, equaling or longer than the filaments; pistillate flowers ebracteolate; pistillate tepals 2, like the staminate; ovary 3-celled, placentae bifid, ovuliferous on all sides, styles connate at base, distinctly divided, the stigmatic surface linear, spiral, continuous; capsule erect or somewhat nutant, broadly ovoid, 6-10 mm. long, wings very unequal, the largest ovate or deltoid, obtuse, to 15 mm. wide, seeds ellipsoid, blunt." (Flora of Guatemala)

Habitat/ecology:  "Damp thickets and forests, alt. 1-1,650 meters...." (Flora of Guatemala)

"After going briefly dormant in the fall, this attractive plant blooms from winter through spring in response to rains, which stimulate new growth. The plant prefers partial shade." (A Tropical Garden Flora, p. 177)

Propagation:  Propagation (horticultural): dividing the rootball; dividing rhizomes, tubers, corms or bulbs (including offsets); leaf cuttings; herbaceous stem cuttings; by seed (allow seedheads to dry on plants; remove and collect seeds); winter sow in vented containers, coldframe, or unheated greenhouse; or simple layering. (Dave's Garden)

Native range:  Mexico (CABI Invasive Species Compendium); Central America and Colombia (Hortipedia)
