From my experience...
Kadsura cocinnea will grow in full sun in a mild climate (Highs in the 70s-80s(F) and lows in the 60s-50s (F), such as coastal SoCal and certain regions of the Mediterranean).
Otherwise, it prefers/appreciates being grown under dappled shade in hot climates (Highs in the 100s-90s(F) and lows in the 80s-70s(F) with high humidity, such as South Texas, South Florida, lowland Puerto Rico, etc...)
Most are very prone to root rot (makes sense considering they like to inhabit mountain slopes in Southeast Asia and Southern China). So avoid growing them in wet, muddy soil...
Once established, they are surprisingly quite resilient!
