Hi flagardener,
I agree with everyone else, it looks like you've got a nice collection of Hoya plants. I too grow a couple of Hoyas and I like them a lot. The easiest for my conditions and care (or lack thereof
) seem to be H. carnosa, H. pubicalyx and H. australis. My plants usually stay outside year round and I have lost a few in extremely cold winters but I just don't have space indoors for all of my plants so the ones outside get old blankets thrown over them if we have frosts or freezes. I currently have a real tiny H. nummularioides plant in one bathroom and another real tiny H. heuschkeliana plant in another bathroom; both are blooming their little heads off and the fragrance is quite nice in the evening and at night! There are large skylights in both of those bathrooms so they get plenty of natural light and seem to do very well.
There have been a few Hoya related discussion threads over on the Houseplants Forum that you may want to check out, or even start a new thread in that forum to chat and share photos:
