Stromanthe sanguinea

A rhizomatous prayer-plant relative from the Brazilian Atlantic Forest, with leaves that are red-purple underneath. Kew now accepts it as Stromanthe thalia, with S. sanguinea as a synonym. It grows in the humid forest understory from the lowlands up into montane forest. It expects shade, constantly moist soil, high humidity and a mild, somewhat drier winter with cooler nights.

Where it grows wild

Understory of the Atlantic rain forest (Mata Atlântica). It is studied in both lowland and montane forest in Rio de Janeiro state, and its leaf anatomy shifts between the two environments. It forms clumps from rhizomes on the humid forest floor.

Recorded elevations run 0–1400 m, with a median of 650 m from 68 records. It spans lowland to lower montane forest.
