    I acquired a small Hoya australis subsp. australis in August, 2008 and it was at least five years later before it showed any blooms. Compared to H. australis subsp. tenuipes, this one has smaller leaves and is not as prolific a bloomer as H. australis subsp. tenuipes, but I love the soft, pubescent leaves on this one. This plant blooms for me between mid November to mid December and the flowers are extremely fragrant in the evening and at night.
