They are tender perennials, typically grown as annuals outside their native Southeast Asia. Coleus plant, also known as Painted Nettle, is often grown outdoors as an annual because it is frost-tender. But it's easy to grow indoors if you can provide bright light. Distinctive leaf shapes, intricate patterns, and rich colors rival some of the showiest foliage plants. Pinch your plant. Coleus plants can get leggy. Pinch growing tips often to encourage them to branch out and stay bushy and full. Also pinch off flower spikes as soon as you notice them because they will detract from the beautiful foliage. Keep it moist. Coleus leaves will wilt and may fall off if the soil is too dry. You'll have a much healthier-looking plant if you keep the soil moist at all times. Use a pot with drainage holes and water thoroughly. Need a container? It's just the thing to keep your coleus from wilting this summer. Dropped leaves? Low light, dry soil or cold air can cause leaves to drop. Don't worry - this vigorous plant will replace them when it gets what it wants.
