Concinna Prayer Plant (Calathea concinna)  - to 14",   This low-growing house plant forms a rosette of striking leaves.  The pale-grey-gren leaves are marked with olive-green, lance-shaped markings that are arranged opposite one another all along the central vein.  During the day, the leaves are held almost horizontally outward from the center, then in the evening, the leaves close up like hands in prayer.  This is one of the smaller Calatheas.  A live plant in a 3" pot - $22 each or 3 for $62.70 - You save $3.30!
