Those easy-to-tend tradescantia and zebrina groups commonly called wandering Jew or inch plant have 1- to 3-inch striped leaves, often with purple undersides. In spring and summer, they bear small clusters of flowers.
They grow well in pots and in hanging baskets in a warm, sunny window. Cool temperatures slow their growth.
Pot them in a standard potting mix. Once or twice monthly during the growing season, give liquid plant food, diluted to half the recommended strength.
In spring and summer, water moderately: in fall and winter, allow the top 1/2 inch of soil to dry between waterings. When the plant becomes root bound, repot it in a larger container. Propagate by tip or stem cuttings any season.
