There was a time when I had one of the most showy Hoya mirabilis Clone B plants in the world; that time has past. In those days, the plant grew semi-hydroponically and flourished. Two years ago I chopped up the plant and sold off all of the cuttings except one plant that was the worst of the lot.  Since then I have done little with it except throw it in the corner of a small grow tent.  Every so often it flowers; this is one of those times.
