The Prayer plant (Maranta leuconeura) is native to the tropical forests of Brazil and is commonly grown as a beautiful indoor houseplant. It has variegated leaves that fold and move to a perpendicular 'prayer' position at night to resemble praying hands. The undersides of the leaves are usually red and/or purple. New leaves appear as a rolled tube.
Common names include Cathedral Windows, Herringbone Plant, Rabbit Tracks, & Red-Veined Prayer Plant.
