Begonia cucullata
A fleshy, upright herbaceous begonia from southern Brazil, Paraguay, Uruguay, north-east Argentina and Bolivia, and one of the wild parents of the common bedding wax begonia. It grows in wet, open places such as stream banks, marshy grassland and forest edges, and flowers most of the year in warm conditions. It is easy, tolerates cooler nights than most begonias, and self-seeds freely.
Where it grows wild
It grows in damp, sunny to lightly shaded places: stream and river banks, wet grassland, swamp margins, forest edges and roadsides. It spreads readily by seed and has become invasive on disturbed ground in Florida and Georgia.
Records span sea level to 2025 m, with a median of 589 m (295 records with elevation). Most are on the southern Brazilian plateau and in the lowlands of the Paraná and Uruguay river basins.
