Hoya lyi Is One Of The Most Cold Tolerant Hoyas

Hoya lyi is found among the furthest north of any Hoya species and can survive temperatures that briefly dip below freezing. I don’t think that I want to try it on my little specimen, but perhaps the reason that it flowered so quickly for me this winter is because my day time temperature rarely got over 74F and night time temps dropped into the upper 50s.
