Gardener query: Jade Vine

A listener, Margaret wanted to know about a plant called the Jade Vine, the latin name is Strongylondon. 

It has these remarkable blue-green flowers on strand that hangs dwn 2-3 metres. The plant comes from the Philippines where it is endangered because of rainforest habitat devastation.

Jade vine will only grow in a true hot house in Melbourne and I have never seen it available to buy in Melbourne.
