Native to the cliffs of Ecuador, it's a very hardy plant suitable for bonsai.  Use it in pots, or, like in the photo at left, on top of a rock, where it will attach itself and crawl along.  Cream-colored, fragrant, button-resembling flowers have resin, not nectar.  Certain bees collect the resin to use to patch holes in the roofs of their hives.  

At right is a photo of the little cliff-hanger naturalizing itself along a recreation of its indigenous environment.
