I do not know the name of the plant but I would like to try it. The leaves are blade shaped and there are 'Babies ' with tiny roots all along the leaves . The babies fall on to the soil and root .
The plant you are referring to may be a Kalanchoe. Maybe chandelier plant or mother of thousands. Check out the link below for pictures of Kalanchoes.
