Kalanchoe Tubiflora ("Mother of Thousands") its bluish flower-like "blooms" are actually small plantlets that will fall off and start new plants. Sometimes called the "Chandelier plant" because of it's it's pendulous blooms.
String of Pearls Plant (Senecio Rowleyanus) I love these.A friend gave me a string of pearls plant several years ago. Mine got somekind of disease and I lost it. Haven't been able to find another since.
