Jen, this may be your plant, not real sure as it's difficult to see any foliage in your picture. Clerodendrum thomsoniae. Commonly called Bleeding Heart Vine or Glory Bower. Rosie Here is a link that might be useful: Clerodendrum thomsoniae

Compare with Corydalis sempervirens.

Ricky, Never let it loose in the garden, it will swallow trees and climb palms. It will also lose it's coloration as it matures and climbs.
