Rarely have we seen a rex begonia with such golden and red foliage. 'Autumn' begonia does indeed appear to have fall colored foliage, with the colors more intense when grown in a well-lighted room. It may appreciate misting to increase the humidity, but should be watered thoroughly only when the surface soil is dry. Pink flowers may appear in the winter, but the foliage is the main attraction. If the plant gets too leggy, consider moving it to a brighter environment, and don't hesitate to pinch back the stems to encourage new growth at the base.
