Hoya diversifolia is Not Free Flowering!

Having picked up after messy Hoyas in the house all summer long, I have developed more of an appreciation for the less free flowering Hoyas.  I have never found this plant to bloom more than once a year for me.  This year I seem to have an abundance of flowers on three or four peduncles, but this is an exceptional year.
