Calatheas (Prayer plants) are known for their bold patterned foliage. The leaves of most Calathea varieties fold up slightly during the night time due to nyctinastic movement, revealing the often colorful undersides of their striking leaves. Calathea Roseopicta "Rosy" has broad, silvery-green leaves that taper to a point edged with a wide band of dark green and reddish mid-rib.
