Callisia is related to the Tradescantia family. It is a straggly, cascading, low-growing plant bearing a multitude of small green, fleshy leaves. In late autumn/winter, as watering slows down or ceases, the leaves become deep purple. Often grown as a houseplant in temperate climates as it is a native of tropical origin. They need a light shaded or bright room but not in direct sunshine.
