This plant is very similar to a burro's tail except the leaves are much thinner, they don't fall off when bumped and they have bulbs. It is slowly dying, I can't get the bulbs to reproduce and putting the leaves in the soil doesn't work either.
Since no Crassulaceae are bulbous and no bulbs are Crassulaceous, you've completely lost me. Posting a picture would be really helpful.
From your description, it sounds like a asteraceae senecio radicans. http://herselfshouseplants.com/2008/05/string-of-bananas-asteraceae-senecio-radicans.html
Asteraceae is the family Senecio radicans belongs to, and not a part of the individual species' name. Family: Asteraceae Genus: Senecio Species: radicans
Senecio radicans doesn't have leaves thinner than Sedum morganianum. It doesn't have bulbs either. Would prefer to see a picture than blind guessing.
