I am trying to find a plant that I had years ago that unfortunately died during a move. It seems like it's a cross between several different types of succulents; the leaves were flattened on the end connected to the vine, but otherwise rounded;they were not close together; there would be a pair on either side of the vine, then about a half an inch to an inch space on the vine before the next pair. It bloomed for me once, and had red spiky flowers, clustered in the center. The vines drooped over the side of the pot then would curve back up towards the sun. Also the vines seemed ropy.
