Both propagate with stem cuttings. Prayer Plant - Cut off that stem as close to the soil as you can and stick it in some dirt just past the knobby bit so it's underneath the soil. That's where the new roots will form. Teddy Bear - Root it the same way you'd root Tradescantia fluminensis. Cut off a long stem and divide it into pieces with at least 2, preferably 3 leaf nodes. Bury the stems covering at least 1 leaf node. Keep the soil moist and the cuttings in bright but not direct light. Prayer Plant should start pushing out roots in about a couple of weeks - soil temperature will determine the swiftness. The Teddy Bear within a day or 2.
