Here are a couple of new photos of Hoya campanulata.  I have come to really like this plant. When grown hot and humid, it is an extremely easy Hoya.  It blooms on average once every three weeks or so.  It is another Hoya that I grow in a conventional mix, and the plant does not seem to mind being kept almost wet.  Maybe it is because it is so darned hot in that room, that it tolerates the wet soil – I have never tried to grow it in the main house, but I suspect that it would go into decline quickly.
