To prove that it was not a fluke, Hoya maxima/imbricata has flowered for the second time for me.  To be fair, this is not an easy Hoya to flower.  On my way towards this second flowering, I have literally lost dozens of buds that have blasted for no discernible reason.  Some of these buds will blast a couple of days before opening – really maddening!  Below is a quick snapshot from this morning along with yet another custom habitat that I set up for the mount.
