OK gang, we have an ID! Rondeletia splendens! Woo Hoo! Thanks to Don Mahoney our director at the greenhouses for the ID!!
It's growing in the 'cloud forest' portion of Strybing Arboretum. It isn't a vine after all but a shrub.
It has a growth habit where it will be about 4' tall, but the branches can grow to 8' but it will weep over in a mounding form.
Here's the Plant Files link to the mystery plant http://davesgarden.com/pf/go/55236/index.html
