Calathea grandifolia

Calathea grandifolia is a large-leaved Brazilian prayer plant that Kew records across northern, central-western, southeastern and southern Brazil. GBIF holds only one usable wild record, near Rio de Janeiro, so the measured climate is that of the Atlantic Forest there: warm and wet in summer, milder and drier in winter. Growers should treat it as a shade herb that likes warmth and humidity but tolerates a cooler winter.

Where it grows wild

A terrestrial understorey herb, inferred from the genus. The one measured site lies in Atlantic Forest on the western side of Rio de Janeiro; habitats elsewhere in its wide Brazilian range are not documented here.

The only record carries no elevation; the measured site is near sea level to low hills around Rio de Janeiro.
