Well done Gordon,
Your plant is a Stepelia Gigantea. It seems mine only blooms when hanging down also. Was told they smell, but I never noticed any on mine. It only bloomed two flowers at a time so maybe it wasn't enought. Also no fly ever seemed to bother it. Yours looks like tiny magots in the center. I was told flys do this. They are completely fooled by the flowers. They pose no harm. After giving away parts many times, mine hasn't bloomed in over two years. Maybe this year. Save those broken pieces for gifts.
