distribution_en:

description_en: Genus of about 300 species of ever-green, rhizomatous perennials found in humid forest and at forest margins in tropical Central and South America, and the West Indies. Most are clump-forming, with ovate to elliptic, shiny, long-stalked, pale to dark green leaves, often attractively patterned and red on the reverse; young plants may differ from mature plants in the size and colour of their foliage. Flowers, rarely produced in cultivation, are tubular with extended upper and lower lips, and are borne in racemes in summer. They have dense spikes of sheathed bracts with pairs of small flowers developing from openings in the sheaths. In frost-prone areas, grow in a warm or temperate greenhouse, or as houseplants; they will tolerate fairly low light levels. In warmer areas, grow in a border or among shrubs.

hardiness_en: Frost tender.

cultivation_en:

propagation_en: Divide clumps in late spring; keep plants in warm, humid conditions until re-established.

pests_en: Aphids and red spider mites may be a problem. Bright light causes leaf scorch; dry air turns leaves brittle and brown at the margins.
