I would have to say that Hoya imperialis is not quite up to the blooming standards of last year, but it still has been blooming non-stop for well over a month now.  I think that three of my really big Hoyas are desperate need of re-potting.  Hoya macgillivrayii, magnifica, and imperialis either need to be re-potted, or started over next spring.  The problem is that after they get so big, it becomes a really daunting chore that requires two people and a lot of nerve – I wasn’t up to the challenge last year, and it is beginning to show with the plants blooming vigor.  Anyway enough chat, here is imperialis from yesterday morning:
