These tropical plants are popular and easy to grow. Grow in full sun and water generously in summer. Stand plants in a drip tray in very shallow water will help keep plants healthy during hot dry spells & spray the leaves with water during cool parts of the day to revitalise the foliage. Lift the tubers or move plants grown in pots indoors when the leaves are first frosted in autumn.
