Does anyone have any info/experience growing Holboellia?

I am looking for that frequently sought ideal plant -an evergreen flowering vine which will grow in complete shade (bed on the north side of house with no sun ever- this is not a spot with some sun in a.m. or p.m., it does not get any sun). I want it to screen from view my neighbor's garage apartment- it will climb on an existing nine foot trellis fence. The soil is quite good and well-draining; it has been extensively amended, and the bed is irrigated. I'm in Zone 9 (Sunset 16) which means pretty mild summers and winters.

Hoelboellia sounds like it might meet these parameters and also look nice, but I've had a hard time finding any info about it. Can you help? Thanks.
