Calathea
Goeppertia spp. (syn. Calathea) · Houseplant
Grown for its boldly patterned leaves, which fold up at night and open again in the morning. It is not hard to keep but dislikes change: dry air, hard water and cold drafts show up quickly as brown edges. A warm, humid, softly lit spot suits it best.
