This is clerodendrum thomsoniae or a similar looking cultivar also called the bleeding heart vine. The genus is found in many tropical areas: Asia, Africa, Australasia and tropical Americas.
It is a weak climber but can be trained into a pillar or grown as a shrub. It does not tolerate frost but in some tropical regions is vigorous enough to have escaped cultivation and become naturalized.
When I grew this plant it was quite happy in a 12 inch pot with lots of diffuse light and water. If grown in a pot this plant gives best performance with flowering plant fertilizer added in the blooming season.
