I have pictured this plant in India in a park. This is a popular plant in India. It is a vine and grow big(atleast 8 ft) Can you help me identify its name? Common as well as botanical name? I want to check with nurseries if they can supply this to me here in the US.
Quisqualis indica http://davesgarden.com/guides/pf/go/31530/ (there are a couple vendors listed in the Plant Files entry) Won't be hardy in NJ though so you'll have to find a way to keep it in a pot and bring it inside for the winter.
