Hoya rotundiflora

This Hoya may be the sweetest one I have.  The leaves are very interesting, with an unusual shape and the flowers are unusual as well. I once saw them described on a Hoya forum as fluffy pillows, which is a perfect description.  I grow this one shaded, and moist.  Last winter it remained outside, with winter night lows regularly in the mid to high 40s during January, and every so often in the high 30s. But the days usually warm up at least 15 degrees. A colder winter didn't seem to hurt the plant at all, although I do keep it a bit drier when it's cold out. It is in a 6 inch pot, filled with Turface/perlite mixture that I use.
