Bella opening sequence

Ever since my Hoya carnosa flowered in May, I haven't seen one peep of a flower from any of my plants (and I've been looking!). So I was so happy to see buds forming and staying on my Bella. I felt even happier when the plant decided to open bud by bud (and I'd figured out how to use the Macro on my camera). It does smell, very faintly.
