Just noticed today both my variegated H. multiflora have lost most of their leaves. We've had a very big rain event, total for January was 1028 mm. They were getting torrential rain virtually daily with no drying out. Some Hoyas have been very happy with it but not the multifloras. They're now on the edge of the carport where they'll be missed by the rain and only get mist blowing in. I'm fairly confident they should recover well.
