I took this photo really quickly this morning.  I had this Hoya outside all summer long in a tent type greenhouse where it did not much at all; I sunburned several leaves, and it did not flower.  After bringing it back indoors, it lost at least 20 large leaves probably because of the radical change in environmental conditions.  Anyhow it recently budded up and has been flowering away now for a few days.  I sold a number of halconensis plants on Ebay early in the summer, and plan to offer them next year as well.
